XC6214 Series

ETR0318_010b

500mA Output Current, High Speed LDO Regulators,
Thermal Shutdown Function, Ceramic Capacitor Compatible

■GENERAL DESCRIPTION

The XC6214 series are highly precise, low noise, high current, positive voltage, low dropout voltage regulators. They are
fabricated using CMOS process. The series features a voltage reference, an error amplifier, a current limiter, a thermal
protection circuit, and a phase compensation circuit plus a driver transistor.
The output voltage is selectable in 1.2V, 1.5V, 1.8V, 2.5V, 3.0V and 3.3V.
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 and the thermal shutdown circuit are built in. The over current protection circuit will
operate when the output current reaches limit current. The thermal shutdown circuit will operate when the junction
temperature reaches limit temperature.

■OPERATIONAL EXPLANATION

<Output Voltage Regulator Control>

The voltage, divided by resistors R1 & R2, which are connected to the V

voltage by the error amplifier. The P-channel MOSFET, which is connected to the V
subsequent output signal. The output voltage at the V
current limit circuit and over current protection operate in relation to the level of output current and heat.

<Low ESR Capacitors>

With the XC6214 series regulator, a stable output voltage is achievable even if low ESR capacitors are used, as a phase
compensation circuit is built-in to the regulator. In order to ensure the stability of the load transient response and line
transient response, we suggest that an output capacitor (C
(V

OUT) and the VSS pin. Please use an output capacitor (CL) with a capacitance more than 0.1μF. We also suggest an

input capacitor (C

<Current Limiter, Short-Circuit Protection>

The XC6214 series regulator offers a combination of current limit and circuit protection by means of a built-in fixed
current limiter circuit and a foldback circuit. When the output pin is shorted, a current of about 50mA flows.

<Thermal Shutdown>

When the junction temperature of the built-in driver transistor reaches the temperature limit level (150℃ TYP.), the
thermal shutdown circuit operates and the driver transistor will be set to OFF. The thermal shutdown function will be
released (automatically recovered) when the junction temperature decreases to the thermal shutdown release
temperature level

■NOTES ON USE

1. Please use this IC within the stated absolute maximum ratings. 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 V

3. Please wire the input capacitor (C

4. Output voltage may increase when the IC is used at light load current (around 0 to 2μA) depending on temperature

conditions, etc.
