A low-dropout or LDO regulator is a DC linear voltage regulator that can regulate the output voltage even when the supply voltage is very close to the output voltage. The advantages of a low dropout voltage regulator over other DC to DC regulators include the absence of switching noise (as no switching takes place), smaller device size (as neither large inductors nor transformers are needed), and greater design simplicity (usually consists of a reference, an amplifier, and a pass element). The disadvantage is that, unlike switching regulators, linear DC regulators must dissipate power, and thus heat, across the regulation device in order to regulate the output voltage.

Low dropout voltage regulator with programmable on-chip output voltage for mixed signal embedded applications
ActiveUS7619402B1Multiple-port networksOne-port networksElectrical resistance and conductanceVoltage generator
A programmable voltage generator has software-programmable registers that may be decoded to generate control bits that turn on select transistors that control a variable resistor network. An external power voltage is input to a regulator transistor, which has a channel resistance controlled by a gate voltage. The channel resistance of the regulator transistor produces a regulated voltage as an output. An op amp compares a reference voltage to a feedback voltage to generate the gate voltage. The feedback voltage is taken from a tap within the variable resistor network. The variable resistor network has select transistors that select one resistor between the regulated voltage and an upper node, and that select one resistor between a lower node and ground. Switches select a tap within a series of resistors between the upper and lower nodes. Y (fine) control bits select the tap while X (coarse) control bits enable select transistors.

Low dropout regulator
InactiveUS20070159146A1Good phase marginMinimize power consumptionElectric variable regulationLow loadEngineering
The present invention provides a low dropout (LDO) regulator with a stability compensation circuit. A “zero frequency” tracking as well as “non-dominant parasitic poles' frequency reshaping” are performed to achieve a good phase margin for the LDO by means of the compensation circuit. In this compensation method neither a large load capacitor nor its equivalent series resistance is needed to stabilize a regulator. LDO regulators, in system on chip application, having load capacitors in the range of few nano-Farads to few hundreds of nano-Farads can be efficiently compensated with this compensation method. A dominant pole for the regulator is realized at an internal node and the second pole at an output node of the regulator is tracked with a variable capacitor generated zero over a range of load current to cancel the effect of each other. A third pole of the system is pushed out above the unity gain frequency of the open loop transfer function with the help of the frequency compensation circuit. The compensation technique is very effective in realizing a low power, low-load-capacitor LDO desirable for system on chip applications.

A linear low dropout voltage regulator is described that makes use of a depletion mode NMOS pass transistor and of a PMOS transistor in series to the NMOS transistor and connected to its drain.

The same PMOS transistor may be used to disable the current in the load without generating a negative voltage at the gate of the depletion pass transistor. This regulator is inherently stable without the need for an output capacitor in parallel to the load.

A current limiting circuit for a linear regulator includes an output stage transistor and a replica transistor, which have gates coupled to receive an output voltage from a linear amplifier and sources coupled to load circuitry. A drain of the output stage transistor is coupled to a VDD supply terminal, while a drain of the replica transistor is coupled to the VDD supply terminal through a first resistor. The output stage transistor and replica transistor are operated in saturation, such that proportional currents flow through these transistors. The voltage drop across the first resistor provides a first voltage, which is applied to a second amplifier. A reference voltage is also applied to the second amplifier. When the first voltage becomes less than the reference voltage, a feedback transistor is enabled to pull down the output voltage of the linear amplifier, thereby limiting the output current supplied to the load circuitry.
