XC62E Series
ETR0311_002
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.

External Components:

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