XC6213 Series

ETR0308_007a

High Speed LDO Regulators, Low ESR Cap. Compatible, Ultra Small Package

■GENERAL DESCRIPTION

The XC6213 series is a highly precise positive voltage LDO regulator with low noise manufactured using CMOS process. The series achieves high ripple rejection and low dropout and consists of a voltage reference, an error amplifier, a current limiter and a phase compensation circuit plus a driver transistor. Output voltage is selectable in 0.05V increments within a range of

1.2V to 5.0V. The series is also compatible with low ESR ceramic capacitors, which give output stability. The current limiter's foldback circuit also operates as a short circuit protection for the output pin. The CE function enables the output to be turned off, resulting in greatly reduced power consumption. Ultra small package SSOT-24, SOT-25, USPN-4 and USP-4 are available.

■OPERATIONAL EXPLANATION

<Output Voltage Regulator Control> The voltage, divided by resistors R1 & R2, which are connected to the V by the error amplifier. The P-channel MOSFET which is connected to the V output signal. The output voltage at the VOUT pin is controlled & stabilized by negative feedback. The current limit circuit and short circuit protection operate in relation to the level of output current. Further, the voltage regulator's internal circuitry can be shutdown via the CE pin's signal.

<Low ESR Capacitor> With the XC6213 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 effectiveness of the phase compensation, please connect an output capacitor (C output capacitor (C

SETTING VOLTAGE 1.2 ~ 1.75V 1.8 ~ 5.0V

CL More than 3.3μF More than 1.0μF

<Short-Circuit Protection> The XC6213 series regulator offers circuit protection by means of a built-in foldback circuit. When the load current reaches the current limit level, the fixed current limiter circuit operates and output voltage drops. As a result of this drop in output voltage, the foldback circuit operates, the output voltage drops further and output current decreases. When the output pin is shorted, a current of about 50mA flows.

<CE Pin> The IC's internal regulator circuitry can be shut down via the signal from the CE pin with the XC6213 series. In shutdown mode, output at the V Pull-Down', operations will become unstable with the CE pin open. We suggest that you use this IC with either a V voltage or a V

■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 (CIN) and the output capacitor (CL) as close to the IC as possible. Should rapid input fluctuation or load fluctuation occur, please increase the capacitor value such as C

4. Make sure not to use the IC with large current at high temperature. When exceeding power dissipation of a package, heat occurs before short protection operates, and the IC may break.
