40 mA LDO voltage regulator (3.3/5.0V to 1.8V)

Overview

180TSMC_LDO_20 is LDO to convert IO voltage 3.0V÷5.5V to 1.8V and designed to supply integrated circuits with stable and precise voltage with load up to 40mA. 

The output voltage can be fine-tuned from +3% to  -4% at nominal value. 

The main feature of this LDO is ultra-low power consumption 1.2uA@VIN=5.0V at 5mA load current.

IP includes Bandgap voltage reference source as well as supplies LDO sub-blocks by PTAT reference current. There is Power-OK circuit to indicate a status about output voltage.
