描述
BD00EA5Wxxx系列是低消耗电流线性稳压器。该IC具有45V耐压，500mA输出电流，17μA消耗电流（典型值）。输出电压精度BD00EA5WFP和BD00EA5WFP为±1％，BD00EA5WFP2为±1.5％（不包括反馈电阻精度）。通过在ADJ引脚上增加一个电阻，可以将输出电压设置为1.2V至16V。有一个输出关闭功能，当EN引脚施加High电压时，IC输出开启，施加LOW电压时输出关闭。该IC具有过流保护功能，可防止因输出短路等导致的IC损坏，以及过热保护电路，可防止IC因过载等原因造成热损坏等。输出相位补偿电容可使用低ESR陶瓷电容器。

General Description

Key Specifications

The BD00EA5Wxxx series are linear regulators designed

as low current consumption products for power supplies in

various automotive applications.

These products are designed for up to 45 V as an absolute

maximum voltage and to operate until 500 mA for the

output current with low current consumption 17 μA (Typ).

 Wide Temperature Range (Tj):

 Wide Operating Input Range:

 Low Current Consumption:

 Output Current Capability:

 High Output Voltage Accuracy:

 Output Voltage:

-40 °C to +105 °C

3 V to 42 V

17 μA(Typ)

500 mA

±1 %(Tj = 25 °C)

1.2 V to 16 V

These can regulate the output with

a very high

accuracy^{(Note 1)}, ±1 % (BD00EA5WFP, BD00EA5WHFP)

and ±1.5 % (BD00EA5WFP2). The output voltage can be

adjusted between 1.2 V and 16 V by an external resistive

divider connected to the adjustment pin. These regulators

are therefore an ideal for any applications requiring a direct

connection to the battery and a low current consumption.

Packages

FP: TO252-5

W(Typ) x D(Typ) x H(Max)

6.5 mm x 9.5 mm x 2.5 mm

A logical “HIGH” at the EN pin turns on the device, and in

the other side, the devices are controlled to disable by a

logical “LOW” input to the EN pin.

The devices feature the integrated Over Current Protection

to protect the device from a damage caused by a short-

circuiting or an overload. These products also integrate

Thermal Shutdown Protection to avoid the damage by

overheating.

HFP: HRP5

9.395 mm x 10.54 mm x 2.005 mm

Furthermore, low ESR ceramic capacitors are sufficiently

applicable for the phase compensation.

(Note 1) The tolerance of feedback resistor is not included.
