Very Low Input, Very Low Dropout, 2-A Regulator With Enable

 

Recommended alternative parts

  • TPS7A92  -  TPS7A92 is 2A, low noise (4.7uVrms) LDO in a small package (2.5 mm x 2.5mm)
  • TPS7A83A  -  The TPS7A83A is 2-A LDO with low-noise (4.4 µVRMS) and low-dropout (200mV) and improved accuracy (0.75%)

Description

The TPS7A7001 is a high-performance, positive-voltage, low-dropout (LDO) regulator designed for applications requiring very low input voltage and very low dropout voltage at up to 2 A. The device operates with a single input voltage as low as 1.425 V, and with an output voltage programmable to as low as 0.5 V. The output voltage can be set with an external resister divider.

The TPS7A7001 features ultra-low dropout, ideal for applications where VOUT is very close to VIN. Additionally, the TPS7A7001 has an enable pin for further reduced power dissipation while in shutdown mode. The TPS7A7001 provides excellent regulation over variations in line, load, and temperature.

The TPS7A7001 is available in an 8-pin SO PowerPAD™ package.
