FAST TRANSIENT RESPONSE, 1-A LOW-DROPOUT VOLTAGE REGULATORS

FEATURES

DESCRIPTION

•

Input Voltage Range: 2.7 V to 10 V

This device is designed to have a fast transient

response and be stable with 10 µF capacitors. This

•

Low-Dropout Voltage: 230 mV typical at 1 A

(TPS76850)

combination provides high performance at

reasonable cost.

•

2% Tolerance Over Specified Conditions for

Fixed-Output Versions

Since the PMOS device behaves as a low-value

resistor, the dropout voltage is very low (typically

230 mV at an output current of 1 A for the TPS76850)

and is directly proportional to the output current.

Additionally, because the PMOS pass element is a

voltage-driven device, the quiescent current is very

low and independent of output loading (typically

85 µA over the full range of output current, 0 mA to

1 A). These two key specifications yield a significant

improvement in operating life for battery-powered

systems. This LDO family also features a shutdown

mode; applying a TTL high signal to EN (enable)

shuts down the regulator, reducing the quiescent

current to less than 1 µA at T_J= 25°C.

Open Drain Power Good (See TPS767xx for

Power-On Reset With 200-ms Delay Option)

•

Ultralow 85 µA Typical Quiescent Current

Available in 1.5-V, 1.8-V, 2.5-V, 2.7-V, 2.8-V,

3.0-V, 3.3-V, 5.0-V Fixed Output and

Adjustable (1.2 V to 5.5 V) Versions
