3 Description

The TPS7A15 is a small, low-dropout regulator (LDO)

with excellent transient response. This device can

source 400 mA with outstanding ac performance (load

and line transient responses). The input voltage range

is from 0.7 V to 2.2 V, and the output range is from

0.5 V to 2.0 V with a very high accuracy of 1 over

load, line, and temperature.

The primary power path is through the IN pin and can

be connected to a power supply as low as 50 mV

above the output voltage. All electrical characteristics

(including excellent output voltage tolerance, transient

response, and PSRR) are specified for input voltages

100 mV greater than the output voltage, thereby

yielding high practical efficiency. This regulator

supports very low input voltages by using a higher,

externally supplied VBIAS rail that powers the internal

circuitry of the LDO. For example, the supply voltage

to the IN pin can be the output of a high-efficiency,

DC/DC step-down regulator and the BIAS pin supply

voltage can be a rechargeable battery.

The TPS7A15 is equipped with an active pulldown

circuit to quickly discharge the output when disabled,

and provides a known start-up state.

The TPS7A15 is available in a 2-mm × 2-mm, 6-pin

WSON package and in an ultra-small 0.71-mm × 1.0-

mm, 6-bump WCSP package.
