BD4XXS5-C中文资料罗姆数据手册PDF规格书

General Description

The BD4xxS5-C series are low quiescent regulators

featuring 45 V absolute maximum voltage, and output

voltage accuracy of ±2 (3.3 V or 5 V: Typ), 500 mA

output current and 38 μA (Typ) current consumption.

These regulators are therefore ideal for applications

requiring a direct connection to the battery and a low

current consumption.

A logical “HIGH” at the CTL enables the device and “LOW”

at the CTL disables the device.

(Only W: Includes Enable Input).

Ceramic capacitors can be used for compensation of the

output capacitor phase. Furthermore, these ICs also

feature overcurrent protection to protect the device from

damage caused by short-circuiting and an integrated

thermal shutdown to protect the device from overheating

at overload conditions.
