描述
BD450S5WFP2-C is low quiescent regulators featuring 45V absolute maximum voltage, and output voltage accuracy of ±2% (3.3V or 5V: Typ), 500mA output current and 38µA (Typ) current consumption. This regulator is 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. Ceramic capacitors can be used for compensation of the output capacitor phase. Furthermore, this IC 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.

Datasheet

For Automotive 45 V Input

500 mA Fixed Output LDO Regulators

BD4xxS5-C Series

General Description

Features

◼ Qualified for Automotive Applications

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.

◼ Wide Temperature Range (Tj):

◼ Wide Operating Input Range:

◼ Low Quiescent Current:

◼ Output Current:

-40 °C to +150 °C

3.0 V to 42 V

38 μA (Typ)

500 mA

◼ High Output Voltage Accuracy:

◼ Output Voltage:

±2 %

3.3 V or 5.0 V (Typ)

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.

◼ Enable Input (Only W: Includes Enable Input)

◼ Overload Current Protection (OCP)

◼ Thermal Shutdown Protection (TSD)

◼ AEC-Q100 Qualified^{(Note 1)}

◼ Functional Safety Supportive Automotive Products

(Note 1): Grade 1
