General Description

Key Specifications

The BD800M5Wxxx-C series are linear regulators

designed as low current consumption products for power

supplies in various automotive applications.

◼ Wide Temperature Range (Tj):

◼ Wide Operating Input Range:

◼ Low Current Consumption:

◼ Output Current Capability:

◼ High Output Voltage Accuracy:

◼ Output Voltage:

-40 °C to +150 °C

3 V to 42 V

17 μA(Typ)

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).

These can regulate the output with a very high accuracy

^{(Note 1)}, ±2 % (BD800M5WFPJ-C, BD800M5WHFP-C) and

±2.6 % (BD800M5WFP2-C). 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.

HRP5

TO263-5

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.

Furthermore, low ESR ceramic capacitors are sufficiently

applicable for the phase compensation.

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

(Note 3) Electrolytic, tantalum and ceramic capacitors can be used.

(Note 4) The tolerance of feedback resistor is not included in the accuracy of output voltage.

(Note 5) The value of a feedback resistor R₁must be within this range.

R₂value is defined by following the formula using the limitation of R₁.

(Note 6) If it needs better transient characteristic, insert a capacitor between

the VOUT and ADJ pins. Refer to Typical Application and Layout Example for the details such as equations.
