For Automotive 20 V Input 500 mA

Adjustable Output LDO Regulators

BDL00A5NUF-C BDL00A5EFJ-C

General Description

Key Specifications

The BDL00A5NUF-C and BDL00A5EFJ-C is a linear

regulator designed as a low current consumption product

for power supplies in various automotive applications.

This product is designed for up to 20 V as an absolute

maximum voltage and to operate until 500 mA for the

output current with low current consumption 30 µA (Typ).

The reference voltage accuracy (ADJ pin voltage

accuracy) is a very high accuracy ^{(Note 1)}, ±2 %. The output

voltage can be adjusted between 1 V and 17 V by an

external resistive divider connected to the ADJ pin.

The output shutdown function is integrated in the devices.

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

the other side, the device is controlled to disable by a

logical “LOW” input to the EN Pin.

◼ Wide Temperature Range (Tj):

◼ Current Consumption:

◼ Shutdown Circuit Current

◼ Output Current Capability:

◼ High ADJ Voltage Accuracy:

◼ Output Voltage:

-40 °C to +150 °C

2.9 V to 18 V

30 µA (Typ)

500 mA

±2 %

1 V to 17 V

(Note 3) It does not contain the current of external feedback resistance.

Applications

◼ Automotive (Power Train, Body ECU)

◼ Car Infotainment System, etc.

The device features the integrated Over Current Protection

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

circuiting or an overload. This product also integrates

Thermal Shutdown Protection to avoid the damage by

overheating.

Package

Furthermore, low ESR ceramic capacitors are sufficiently

applicable for the phase compensation.

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

(Note 4) Electrolytic capacitor, tantalum capacitor and ceramic capacitors can be used. Set capacitor value which do not fall below C_IN=1.0 µF,

C_OUT= 1.0 µF. These values need to consider the temperature characteristics and DC bias characteristics.

(Note 5) The tolerance of feedback resistor is not included in the accuracy of output voltage.

The value of a feedback resistor R₂must be within this range. R₁value is defined by following the formula using the limitation of R₁.

〇Product structure : Silicon integrated circuit 〇This product has no designed protection against radioactive rays.
