描述
The BD4xxS2-C series are low quiescent regulators featuring 45V absolute maximum voltage, and output voltage accuracy of ±2% (3.3V or 5.0V: Typ), 200mA output current and 40µA (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 pin enables the device and “LOW” at the CTL pin not enables the device. (Only W: Includes switch) 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.

Datasheet

For Automotive 45 V Input

200 mA Fixed Output LDO Regulators

BD4xxS2-C Series

General Description

Features

◼ Qualified for Automotive Applications

The BD4xxS2-C series are low quiescent regulators

featuring 45 V absolute maximum voltage, and output

voltage accuracy of ±2 % (3.3 V or 5.0 V: Typ), 200 mA

output current and 40 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

40 μA (Typ)

200 mA

◼ High Output Voltage Accuracy:

◼ Output Voltage:

±2 %

3.3 V or 5.0 V (Typ)

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

“LOW” at the CTL pin not enables the device.

(Only W: Includes switch)

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)

◼ Over Current Protection (OCP)

◼ Thermal Shutdown Protection (TSD)

◼ AEC-Q100 Qualified^{(Note 1)}

◼ Functional Safety Supportive Automotive Products

(Note 1): Grade 1
