LDO Regulator

描述 Description

BD394□FP Series regulators feature a high 36 V breakdown voltage and are compatible with onboard vehicle microcontrollers. They offer an output current of 500 mA while limiting dark current to 30 µA (TYP). The series supports the use of ceramic capacitors as output phase

compensation capacitors. Since the ICs use P-channel DMOS output transistors, increased loads do not result in increased total supply current. BD394□FP Series is ideal for lowering current consumption and costs in battery direct-coupled systems.

特性 Features

1) Super-low dark current: 30 µA (Typ.)

2) Low-saturation voltage type P-channel DMOS output transistors

Output on resistance: 1.6 Ω(Typ.)

3) High precision output voltage: 5 V ±2 (Ta = 25°C) / Iomax = 500 mA

4) Low-ESR ceramic capacitors can be used as output capacitors

5) Vcc power supply voltage = 36 V / Peak power supply voltage = 50 V (tr ≥1 ms, tH ≤200 ms)

6) Built-in over current protection circuit and thermal shutdown circuit

7) TO252-3/HRP-5/TO220FP-3 package

Applications

Vehicle equipment, car stereos, satellite navigation systems, etc.
