XC6234 Series
ETR03067-002
200mA High Speed LDO Regulator with ON/OFF Switch
■GENERAL DESCRIPTION
The XC6234 series is a 200mA high speed LDO regulator that features high accurate, high ripple rejection and low dropout.
The series consists of a voltage reference, an error amplifier, a driver transistor, a current limiter, a phase compensation circuit
and an inrush current protection circuit.
The output voltage is selectable from 1.2V, 1.5V, 1.8V, 2.5V, 2.8V, 3.0V and 3.3V.
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 series is also compatible with low ESR ceramic capacitors, which provides stable output voltage. This stability can be
maintained even during load fluctuations due to the excellent transient response.
The over current protection circuit is integrated and operates 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 control 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 voltage and output current.
XC6234 Series, Type H
< Low ESR Capacitor>
The XC6234 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).
<Current Limiter, Short-Circuit Protection >
The XC6234 series has current limiter and droop shape of fold-back circuit. When the load current reaches the current limit,
the droop current limiter circuit operates and the output voltage drops with keeping the load current. After that, the output
voltage drops to a certain level, the fold-back circuit operates and the output current goes to decrease with a degree of output
voltage decreasing. The output current finally reaches at the level of 60mA (TYP.) when the output pin is short-circuited.
<CE Pin>
The IC's internal circuitry can be shutdown via the signal of the CE pin.
The XC6234 series has a pull-down resistor at the CE pin inside. Even the CE pin is left open, the CE pin is fixed as Low level.
However, inflow current is generated into the CE pin.

■OPERATIONAL EXPLANATION (Continued)
<CL High-speed Discharge Function>
The N-ch transistor located between the VOUT pin and the VSS pin and the CL discharge resistance is set to 270Ω (TYP.)
when VIN is 5.5V (TYP.) and VOUT is 2.0V (TYP.).
This N-ch transistor can quickly discharge the electric charge at the output capacitor (CL), when a low signal is inputted to
the CE pin. Moreover, discharge time of the output capacitor (CL) is set by the CL auto-discharge resistance (RDCHG) and the
output capacitance (CL).
By setting time constant of a CL auto-discharge resistance (RDCHG) and an output capacitance (CL) as τ(τ= CL x RDCHG), the
output voltage after discharge via the N-ch transistor is calculated by the following formula.
-t / τ
V=VOUT( E )×e
V: Output voltage after discharge
VOUT( E ): Output voltage
t: Discharge time
τ: RDCHG×CL
CL: Output capacitance
RDCHG: CL auto-discharge resistance
or discharge time is calculated by the next formula.
t =τln (VOUT( E ) / V)
< Inrush Current Prevention >
The inrush current prevention circuit is built in the XC6234 series.
When the IC starts to operate, the prevention circuit limits the inrush current as 95mA (TYP.) from input pin (VIN) to output pin
(VOUT) for charging CL capacitor. However, the device can not provide the output current beyond 95mA (TYP.) for a period of
approximately 100μs because internal control of the IC.

■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 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.
4. Torex places an importance on improving our products and their reliability.
We request that users incorporate fail-safe designs and post-aging prevention treatment when using Torex products in their
systems.
