TLV702-Q1 (ACTIVE) Automotive 300mA Low-Iq, High PSRR Low-Dropout (LDO) Regulator

 

Description

The TLV702-Q1 series of low-dropout (LDO) linear regulators are low quiescent current devices with excellent line and load transient performance. These LDOs are designed for power-sensitive applications.

A precision bandgap and an error amplifier provide overall 2% accuracy. Low output noise, very high power-supply rejection ratio (PSRR), and low-dropout voltage make this series of devices ideal for a wide selection of battery-operated equipment. All device versions have thermal shutdown and current limit protections for safety.

Furthermore, these devices are stable with an effective output capacitance of only 0.1 µF. This feature enables the use of cost-effective capacitors that have higher bias voltages and temperature derating. The devices regulate to specified accuracy with no output load.

The TLV702-Q1 series of LDO linear regulators is available in SOT and WSON packages.
