TPS7A03

SBVS375B –JULY 2019–REVISED APRIL 2020

TPS7A03 Nanopower I_Q, 200-nA, 200-mA, Low-Dropout Voltage Regulator With Fast

Transient Response

1 Features

3 Description

The TPS7A03 is an ultra-small, ultra-low quiescent

current low-dropout linear regulator (LDO) that can

source 200 mA with excellent transient performance.

•

Ultra-low I_Q: 200 nA (typ), even in dropout

Shutdown I_Q: 3 nA (typ)

•

Excellent transient response (1 mA to 50 mA)

The TPS7A03, with an ultra-low I_Qof 200 nA, is

designed specifically for applications where very-low

quiescent current is a critical parameter. This device

maintains low I_Qconsumption even in dropout mode

to further increase the battery life. When in shutdown

or disabled mode, the device consumes ultra-low,

3-nA I_Qthat helps increase the shelf life of the

battery. The TPS7A03 has an output range of 0.8 V

to 5.0 V available in 50-mV steps to support the lower

core voltages of modern microcontrollers (MCUs).

•

Input voltage range: 1.5 V to 6.0 V

Output voltage range: 0.8 V to 5.0 V (fixed)

Output accuracy: 1.5% over temperature

Smart enable pulldown

The TPS7A03 features a smart enable circuit with an

internally controlled pulldown resistor that keeps the

LDO disabled even when the EN pin is left floating

and helps minimize the external components used to

pulldown the EN pin. This circuit also helps minimize

the current drawn through the external pulldown

circuit when the device is enabled.

Very low dropout:

–

270 mV (max) at 200 mA (V_OUT= 3.3 V)

•

Stable with a 1-µF or larger capacitor

The TPS7A03 is fully specified for T_J= –40°C to

+125°C operation.
