LDOs consume minimal quiescent current

30 May 2022 Power Electronics / Power Management

The recently introduced AP7387 series from Diodes Incorporated has a wide 5 V to 60 V input voltage range with an extremely low 2 µA quiescent current, making the device a good choice for multi-cell battery-powered applications and other equipment where standby current consumption is important.

This high VIN LDO also has a high 70 dB PSRR (at 1 kHz) coupled with very fast line/load transient response, providing it with the ability to reject rapid input voltage and load current changes, thereby making it suitable for noise-sensitive industrial applications. The AP7387 has a maximum 150 mA output current and is available in 3,0 V, 3,3 V, 3,6 V and 5 V fixed output voltage versions with ±2% output tolerance. The device also includes current limit, short-circuit and thermal shutdown protections.

The AP7387 is available in packages including SOT23, SOT25, SOT89 and U-DFN2020-6, to suit different application requirements.
