XC6224 Series
ETR0340-005
1.2V Low Voltage Operation,150mA High Speed LDO Voltage Regulator
■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.
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 C quickly returns to the V
The over current protection circuit is integrated and operates when the output current reaches current limit level.
■APPLICATIONS

●Digital still cameras
●Portable electronic devices
●Portable media players
●Bluetooth
●Wireless LAN
●Terrestrial digital TV tuners

■ OPERATIONAL EXPLANATION
(1) XC6224Axxxxx
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 V at the V protection operate in relation to the level of output current. Further, the IC’s internal circuitry can be shutdown via the CE
■ NOTES ON USE
OUT pin is controlled and stabilized by a system of negative feedback. The current limit circuit and short circuit
in signal.
<Low ESR Capacitor>
The XC6224 needs an output capacitor C to ensure the stable phase compensation, please place an output capacitor C as possible. For a stable power input, please connect an input capacitor C 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 V be pulled down to the V
SS 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
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 C
IN and the output capacitor CL should be placed to the IC as close as possible with a shorter wiring.
OUT pin is then driven by the subsequent output signal. The output voltage

● 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 Board: Dimensions 40 x 40 mm (1600 mm
Material: Glass Epoxy (FR-4) Thickness: 1.6 mm Through-hole: 4 x 0.8 Diameter
2. Power Dissipation vs. Ambient temperature
Board Mount (Tj max = 125℃)
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.
