Diodes Incorporated AP7387Q Automotive µLDO Regulators

Diodes Incorporated AP7387Q Automotive µLDO Regulators feature a 5V to 60V wide input voltage range, a low quiescent current, and a high PSRR. The AP7387Q offers a 150mA output current and supplies a high-speed line/load transient response against the rapid input voltage and load current changes.

The AP7387Q Automotive µLDO Regulators incorporate a voltage reference, an error amplifier, a resistor network for setting output voltage, a current limit circuit for current protection, short-circuit, and thermal shutdown protection.

The AP7387Q provides 3.0V, 3.3V, 3.6V, and 5V fixed output voltage versions and is housed in the SOT89 and U-DFN2020-6 (SWP) (Type UXC) packages.
