XC6224 Series
ETR0340-004
150mA High Speed LDO Voltage Regulator with ON/OFF Switch
■GENERAL DESCRIPTION
The XC6224 series is a high speed LDO regulator that features high accurate, low noise, high ripple rejection, low dropout
and low power consumption. The series consists of a voltage reference, an error amplifier, a driver transistor, a current limiter,
and a phase compensation circuit.
This IC is suitable for a local power supply placed in adjacent to the system logic LSI or others, because of low input voltage
operation, using an ultra small package USPN-4B02 (0.75mm x 0.95mm) and stable operation with a small phase
compensation capacitor (CL) 0.47μF.
Also, this IC has fast transient response and high ripple rejection (70dB @ 1kHz).
The CE function enables the circuit to be in stand-by mode by inputting low level signal. In the stand-by mode, the series
enables the electric charge at the output capacitor CL to be discharged via the internal switch, and as a result the VOUT pin
quickly returns to the VSS level.
The over current protection circuit is integrated and operates when the output current reaches current limit level.

■ OPERATIONAL EXPLANATION
(1) XC6224Axxxxx
(2) XC6224Bxxxxx
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 and stabilized by a system of negative feedback. The current limit circuit and short circuit
protection operate in relation to the level of output current. Further, the IC’s internal circuitry can be shutdown via the CE
pin signal.
<Low ESR Capacitor>
The XC6224 needs an output capacitor CL and a built-in phase compensation circuit for phase compensation. In order
to ensure the stable phase compensation, please place an output capacitor CL of 0.47μF or bigger at the VOUT pin as close
as possible. For a stable power input, please connect an input capacitor CIN of 0.47μF between the VIN pin and the VSS
pin.
<Current Limiter, Short-Circuit Protection>
The protection circuit operates as a combination of an output current limiter and fold-back short circuit protection.
When load current reaches the current limit level, the output voltage drops. As a result, the load current starts to reduce
with showing fold-back curve. The output current finally falls at the level of 35mA when the output pin is short-circuited.
<CE Pin>
The IC's internal circuitry can be shutdown via the signal from the CE pin. In shutdown mode, output at the VOUT pin will
be pulled down to the VSS level in the XC6224B series. When the CE pin is open, the output voltage becomes undefined
state in the XC6224A series because of a high active and no pull-down. Although the CE pin is equal to CMOS input
configuration, the CE pin input current which flows into a pull-down resistor will increase in the XC6224B series
■ NOTES ON USE
1． For temporary, transitional voltage drop or voltage rising phenomenon, the IC is liable to malfunction should the ratings
be exceeded.
2. Torex places an importance on improving our products and its reliability.
However, by any possibility, we would request user fail-safe design and post-aging treatment on system or equipment.
3. Where wiring impedance is high, operations may become unstable due to the noise and/or phase lag depending on
output current. Please strengthen VIN and VSS wiring in particular.
4. The input capacitor CIN and the output capacitor CL should be placed to the IC as close as possible with a shorter wiring.

USPN-4B02 Power Dissipation
Power dissipation data for the USPN-4B02 is shown in this page.
The value of power dissipation varies with the mount board conditions.
Please use this data as one of reference data taken in the described condition.
1.
Measurement Condition (Reference data)
Condition: Mount on a board
Ambient: Natural convection
Soldering: Lead (Pb) free
し
Board:
Dimensions 40 x 40 mm (1600 mm2 in one side)
Copper (Cu) traces occupy 50% of the front and 50% of the back.
The copper area is divided into four block,
one block is 12.5% of total.
The USPN-4 package has for terminals.
Each terminal connects one copper block in the front
and one in the back.
