The series achieves high ripple rejection and low dropout and consists of a standard voltage source, an error correction, current limiter and a phase compensation circuit plus a driver transistor. Output voltage is selectable in 50mV steps within a range of 0.9V ~ 6.0V. The series is also compatible with low ESR ceramic capacitors which give added output stability. This stability can be maintained even during load fluctuations due to the excellent transient response of the series. The current limiter's foldback circuit also operates as a short protect for the output current limiter and the output pin. The CE function enables the output to be turned off, resulting in greatly reduced power consumption.

In order to ensure the effectiveness of the phase compensation, we suggest that an output capacitor (CL) is connected as close as possible to the output pin (VOUT) and the VSS pin. Please use an output capacitor with a capacitance value of at least 1F. Also, please connect an input capacitor (CIN) of 0.1F between the VIN pin and the VSS pin in order to ensure a stable power input. Recommended output capacitor values VOUT 0.9V ~ 1.2V 1.25V ~ 1.75V CL 4.7F 2.2F 22 XC6204/6205 Series OPERATIONAL EXPLANATION (Continued) The XC6204/05 series includes a combination of a fixed current limiter circuit & a foldback circuit, which aid the operations of the current limiter and circuit protection. 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, output voltage drops further and output current decreases. When the output pin is shorted, a current of about 50mA flows. However, when the input/output voltage differential is quite small, this current will be about 200mA. The IC's internal circuitry can be shutdown via the signal from the CE pin with the XC6204/05 series. In shutdown mode, output at the VOUT pin will be pulled down to the VSS level via R1 & R2. The operational logic of the IC's CE pin is selectable (please refer to the selection guide). Note that as the standard XC6204/05B type is ' High Active/No Pull Down', operations will become unstable with the CE pin open. Although the CE pin is equal to an inverter input with CMOS hysteresis, with either the pull-up or pull-down options, the CE pin input current will increase when the IC is in operation. We suggest that you use this IC with either a VIN voltage or a VSS voltage input at the CE pin. If this IC is used with the correct specifications for the CE pin, the operational logic is fixed and the IC will operate normally. However, supply current may increase as a result of through current in the IC's internal circuitry if a voltage between 0.25V and 1.5V is input. In order to stabilize the IC's operations, an input voltage of more than 2.0V is needed. Should the input voltage be less than 2.0V, the output voltage may not be regulated correctly. (Please refer to Input Voltage vs. Output Voltage characteristics below.) When VIN is less than 2.0V, the CE pin remains in stand-by mode. When VIN rises above 2.0V, the power supply will turn ON. The input power supply will begin to rise after a few hundred msec. (Please also refer to the transient response characteristics.)

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.
