BIPOLAR ANALOG INTEGRATED CIRCUIT µµµµPC2250 SERIES LOW-SATURATED STABILIZED POWER SUPPLY WITH SYSTEM RESET PIN Document No. G14451EJ2V0DS00 (2nd edition) Date Published December 1999 N CP(K) Printed in Japan DATA SHEET © 1999
DESCRIPTION
The µPC2250 series is a collection of low-saturated 4-pin stabilized power supplies with a pin that outputs a reset signal when a drop in the input voltage is detected. Because the reverse leakage current of these power supplies is about 1 µA even if a voltage is applied to the output pin when the input voltage is cut off, these power supplies are ideal for systems with on-board microprocessors requiring battery backup. FEATURES PIN CONFIGURATION (Marking Side)
- Low minimum voltage difference between input and output VDIF = 0.15 V TYP. (at IO = 40 mA)
- Outputs reset signal (active-low) when the input voltage or output voltage drops.
- Low reverse leakage current during back up IOLK = 1 µA TYP.
- Low circuit operating current under no load IBIAS = 1.3 mA TYP.

Where TJ > 150°C, an internal protection circuit cuts off the output. Caution If any of the parameters exceeds the absolute maximum ratings, even momentarily, the quality of the product may be impaired. The absolute maximum ratings are values that may physically damage the product(s). Be sure to use the product(s) within the ratings. STANDARD CONNECTION INPUT INPUT Output Backup capacitor (for backup) Reset output 0.33 F C IN D 1 C O D 2 C DLY GND RESET OUTPUT µ C IN : Determine the capacitance depending on the line between the power supply smoothing circuit and input pin. Be sure to connect this capacitor to prevent abnormal oscillation. Use of a capacitor, such as a film capacitor, with excellent voltage and temperature characteristics is recommended. Note that some laminated ceramic capacitors have poor temperature and voltage characteristics. When using a laminated ceramic capacitor, the capacitance must be stable in the voltage and temperature ranges used. C O : Must be 10 µF or more. Be sure to connect this capacitor to prevent oscillation and to improve transient load stability. Connect CIN and CO as close to the IC (within 1 to 2 cm) as possible. D 1, D2 : Connect Schottky barrier diodes (with a low forward voltage) if the voltage on the OUTPUT and RESET pins is lower than that on the GND pin.
