Boosting Voltage Regulators

■GENERAL DESCRIPTION

The XC62E series are a group of positive output voltage regulators that can supply up to 1A of output current using an

external transistor. Low power and high accuracy are achieved through CMOS process and laser trimming technologies.

The series consists of a high precision voltage reference, an error correction circuit and a short-circuit protected output driver.

In stand-by mode, supply current can be dramatically cut. Since the input-output voltage differential is small, loss control

efficiency is good.

The XC62E is particularly suited for use with battery operated portable products, and products where supply current

regulation is required.

The series are available in an ultra small SOT-25 package.

In connection with the CE function, apart from the negative logic XC62EP series, a positive logic XC62ER series (custom) is

also available.

■TYPICAL APPLICATION CIRCUIT

●Standard Circuit

PNP Tr

RBE

EXT

Vss

External Components:

VIN

RＬ

VOUT

（Tantalum）

PNP Tr.: 2SA1213

（Tantalum）

RBE: 20kΩ ~ 47kΩ

RB: Please refer to Note 2 on the following page.

CIN: 10μF (Tantalum)

CL: 47μF (Tantalum) 10μF minimum

■OPERATIONAL EXPLANATION

Output voltage (VOUT) can be fixed by revising the external transistor's base current. This can be done by comparing the

detected voltage level and the setting voltage power supply level.

With the XC62EP (CE negative voltage), if a voltage above the CE pin's "H" level is applied, the IC will enter stand-by mode

where the base and differential amplifier's currents are regulated.

■NOTES ON USE

1. PNP Transistor

The selection of a transistor should take into account output current, input voltage and power dissipation for each specific

application. It is recommended that a transistor that has a low output saturated voltage (VCE) and high hFE

characteristics be used.

2. RB Resistor

Although the IC unit is protected by a base current remitter circuit, it is recommended that a resistor (RB) be connected

between the transistor's base and the IC's EXT pin to protect the transistor.

Required output current can be calculated using the following equation although characteristic variations and conditions

of use should be carefully checked before use. The following equation also indicates the conditions needed to obtain IOUT

(MAX.) at VIN (MIN.). However, the larger the input current, the larger the output current (IOUT) that can be obtained.

VIN (MIN.)-1.2(V)

0.7(V)

RBE

IOUT (MAX.)

hFE

3. RBE Resistor, CL Capacitor

To prevent oscillation due to output load variation, use of a phase compensation capacitor CL is recommended. Please

use a Tantalum capacitor of at least 10mF. Please also use an RBE resistor of less than 47kΩ.

An RBE resistor of between 20kΩ and 47kΩ is recommended for less power consumption.

4. Input Impedance

In order to control oscillation brought about as a result of impedance at the power supply line, connect a capacitor of

10μF or more (Tantalum) between the external transistor's emitter and the ground pin.

●Protection Circuit

The built-in protection circuit is to protect the IC only. Therefore to prevent output shorts and overshoot current through

the transistor, use of a resistor RB or an overshoot current protection circuit is recommended.

Care should also be taken with the transistor's power dissipation.
