TLV733P-Q1 (ACTIVE)

Automotive capacitor-free 300-mA LDO regulator with foldback current limit for portable devices

 

Description

The TLV733P-Q1 family of low dropout (LDO) linear regulators are ultra-small, low quiescent current LDOs that can source 300 mA with good line and load transient performance. These devices provide a typical accuracy of 1%.

The TLV733P-Q1 family is designed with a modern capacitor-free architecture to ensure stability without an input or output capacitor. The removal of the output capacitor allows for a very small solution size, and can eliminate inrush current at startup. Furthermore, the TLV733P-Q1 family is also stable with ceramic output capacitors if an output capacitor is necessary. The TLV733P-Q1 family also provides foldback current control during device power-up and enabling if an output capacitor is used. This functionality is especially important in battery-operated devices.

The TLV733P-Q1 family provides an active pulldown circuit to quickly discharge output loads when disabled.

The TLV733P-Q1 family is available in the 6-pin DRV (WSON) and 5-pin DBV (SOT-23) packages.
