Description

The TPS7A14C is a small, ultra low-dropout regulator (LDO) with excellent transient response. This device sources 1A with outstanding ac performance (load and line transient responses). The input voltage range is 0.7V to 2.2V, and the output range is 0.5V to 2.0V with excellent accuracy over load, line, and temperature.

The primary power path is through the IN pin, which is connected to a power supply as low as 50mV above the output voltage. All electrical characteristics 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.

The TPS7A14C is equipped with an active pulldown circuit to quickly discharge the output when disabled, and provides a known start-up state.

The TPS7A14C is available in an ultra-small 0.71mm × 1.16mm, 6-bump WCSP package.
