The TLV7A03 is an ultra-small, ultra-low quiescent current low-dropout linear regulator (LDO) that sources 200mA with excellent transient performance.

The TLV7A03, with an ultra-low IQ of 250nA, is designed specifically for applications where very low quiescent current is a critical parameter. This device maintains low IQ consumption even in dropout mode to further increase battery life. When in shutdown or disabled mode, the device consumes only 3nA IQ, which helps increase battery shelf life. The TLV7A03 has an output range of 0.8V to 5.0V, available in 50mV steps, to support the lower core voltages of modern microcontrollers (MCUs).

The TLV7A03 features a smart enable circuit with an internally controlled pulldown resistor that keeps the LDO disabled even when the EN pin is floating. This circuit also helps minimize the external components used to pulldown the EN pin. This circuit also helps minimize the current drawn through the external pulldown circuit when the device is enabled.

The TLV7A03 is fully specified for TJ = –40°C to +125°C operation.
