LDO accepts 60V for consumer products

Author: EIS Release Date: Mar 31, 2022

Diodes has introduced an LDO that works from5 to 60V and has PSRR (power supply rejection ratio) of 70dB at 1kHz.

 

Diodes AP7387 LDO

Called AP7387, ground current is typically 2µA (Vin = 12V, no load), typically staying below 8μA (60Vin 125°C is worst case).

 

There are four versions, with ±2% fixed outputs of 3.0, 3.3, 3.6 or 5V- so, strictly speaking, only the 5V version is an LDO and the rest being non-low-drop-out linear regulators.

 

Minimum drop-out is 850mV max at 100mA and 1.35Vmax at the maximum load current of 150mA.

 

Current limit, short-circuit and thermal shut-down protections are included, and the devices meet 4kV HBM (human body model) ESD (electrostatic discharge) requirements.

 

There are four package types: SOT25 (59.5°C/W junction to case), SOT23 (140.5), SOT89 (97) or U-DFN2020-6 (Type C, 15.5°C/W).

 

Use is expected in cordless vacuum cleaners, smoke detectors and power tools.
