XC62HSeries
ETR0312_006
Positive Voltage Regulator with (Output ON/OFF)
■GENERAL DESCRIPTION
The XC62H series are highly precise, low power consumption, positive voltage regulators, manufactured using CMOS and
laser trimming technologies. The series consists of a high precision voltage reference, an error correction circuit, and an
output driver with current limitation.
By way of the CE function, with output turned off, the series enters standby. In the stand-by mode, power consumption is
greatly reduced.
SOT-25 (150mW), SOT-89-5 (500mW) and USP-6B (120mW) packages are available.

■PIN CONFIGURATION
*The dissipation pad for the USP-6B
package should be solder-plated in
recommended mount pattern and
metal masking so as to enhance
mounting strength and heat release.
If the pad needs to be connected to
other pins, it should be connected to
the VIN (No.1) pin.

XC62H Series
■OPERATIONAL EXPLANATION
Output voltage control with the XC62H series:
The voltage divided by resistors R1 & R2 is compared with the internal reference voltage by the error amplifier.
The P-channel MOSFET, which is connected to the VOUT pin, is then driven by the subsequent output signal.
The output voltage at the VOUT pin is controlled & stabilized by a system of negative feedback.
The current limit circuit operate in relation to the level of output current.
< Current Limiter >
The XC62H series has output current limiter of fixed current limiter circuit. When the output current reaches the current limit, the
fixed current limiter circuit operates and the output voltage drops with keeping the output current.
<CE Pin>
The IC's internal circuitry can be operated or shutdown via the signal from the CE pin with the XC62H series. In shutdown
mode, output at the VOUT pin will be pulled down to the VSS level via R1 & R2. Note that the XC62H series’ regulator is “High
Active/No Pull-Down”, operations will become unstable with the CE pin open. We suggest that you use this IC with either a
CE High level voltage or a CE Low level voltage input at the CE pin. If this IC is used with the correct specifications for the CE
pin, the operational logic is fixed and the IC will operate normally. However, supply current may increase as a result of
through current in the IC's internal circuitry.
＜Input and Output Capacitors＞
The XC62H series needs an output capacitor (CL) for phase compensation. In order to ensure the stable phase compensation,
please place an output capacitor of 1.0μF at the VOUT pin and VSS pin as close as possible. For a stable power input, please
connect an input capacitor (CIN) of 1.0μF between the input pin (VIN) and the ground pin (VSS).
■NOTES ON USE
1. Please use this IC within the stated maximum ratings. For temporary, transitional voltage drop or voltage rising phenomenon,
the IC is liable to malfunction should the ratings be exceeded.
2. Where wiring impedance is high, operations may become unstable due to noise and/or phase lag depending on output current.
Please strengthen VIN and VSS wiring in particular.
3. Please wire the input capacitor (CIN) and the output capacitor (CL) as close to the IC as possible.
Should rapid input fluctuation or load fluctuation occur, please increase the capacitor value such as CIN or CL to stabilize the
operation.
4. Torex places an importance on improving our products and their reliability.
