3 Description

The TPS7A15C is a small, low-dropout regulator (LDO) with excellent transient response. This device can source 400mA with outstanding ac performance (load and line transient responses). The input voltage range is from 0.7V to 2.2V, and the output range is from 0.5 V to 2.0V.

The primary power path is through the IN pin and can be connected to a power supply as low as 50mV above the output voltage. All electrical characteristics (including excellent output voltage tolerance, transient response, and PSRR) are specified for input voltages 100mV 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.

This LDO is equipped with an active pulldown circuit to quickly discharge the output when disabled, and provides a known start-up state.

The TPS7A15C is available in an ultra-small 0.71mm × 1.0mm, 6-bump WCSP package.
