XC6228 Series
ETR0360-002
300mA High Speed LDO Regulator with ON/OFF Switch
■GENERAL DESCRIPTION
The XC6228 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, a
phase compensation circuit.
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 output stabilization capacitor CL is also compatible with low ESR ceramic capacitors.
The output voltage is selectable from 1.2V, 1.5V, 1.8V, 2.5V, 2.8V, 3.0V, 3.1V, 3.3V which fixed by laser trimming technologies.
The over current protection circuit is built-in. This protection circuit will operate when the output current reaches current limit
level.

■ OPERATIONAL EXPLANATION
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 and heat dissipation.
Further, the IC’s internal
circuitry can be shutdown via the CE pin signal.
The XC6228 series needs an output capacitor CL for phase compensation.
and the ground pin (VSS) as close as possible.
Please place an output capacitor (CL) at the output pin (VOUT)
Please use the output capacitor (CL) is 1.0μF or larger.
For a stable power input, please
connect an input capacitor (CIN) of 1.0μF between the VIN pin and the VSS pin.
The XC6228 has current limiter and droop shape of fold-back circuit.
limiter circuit operates and the output voltage drops.
goes to decrease.
When the load current reaches the current limit, the droop current
When the output voltage dropped, the fold-back circuit operates and the output current
The output current finally falls at the level of 50mA when the output pin is short-circuited.
The IC's internal circuitry can be shutdown via the signal from the CE pin. In shutdown mode, the XC6228 series enables the electric charge
at the output capacitor (CL) to be discharged via the internal switch located between the VOUT and VSS pins, and as a result the VOUT pin
quickly returns to the VSS level.
The XC6228 series has a pull-down resistor at the CE pin inside, so that the CE pin input current flows.
■ 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. 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.
3. The input capacitor CIN and the output capacitor CL should be placed to the as close as possible with a shorter wiring.
4. 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.
