Nanopower-IQ 200nA 200mA low-dropout (LDO) voltage regulator with fast transient response | DBV | 5 | -40 to 125

The TPS7A03 is an

ultra-small, ultra-low quiescent current low-dropout linear regulator (LDO) that

sources

200mA with excellent transient performance.

The TPS7A03, with an

ultra-low IQ of 200nA, is designed specifically for

applications where very-low quiescent current is a critical parameter. This device

maintains low IQ consumption even in dropout mode to further increase

battery life. When in shutdown or disabled mode, the device consumes ultra-low, 3nA

IQ that helps increase

battery

shelf

life.

The TPS7A03 has an output range of 0.8V to 5.0V available in 50mV

steps to support the lower core voltages of modern microcontrollers (MCUs).

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.

This circuit also 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.

The TPS7A03 is fully

specified for TJ = –40°C to +125°C operation.
