ICL7664

The ICL7664 is designed as one kind of high effciency negative voltage regulator with a quiescent current of less than 10 uA. The output voltage is set by two external resistors to any voltage in the -1.3 V to -16 V range, with an input voltage range of -2V to -16V. The ICL7664 is well suited for battery powered supplies, with a 10 uA quiescent current, an output current capability of 25 mA, low Vin to Vout differential, current limiting, and a logic input level shutdown control.

Features of the ICL7664 are:(1)1% output voltage accuracy;(2)-2V to -16V operating range;(3)25 mA output current, with current limiting;(4)adjustable output voltage;(5)low input to output voltage drop;(6)low power CMOS: 4 uA quiescent current. And this device can be used in handheld instruments, LCD display modules and systems, pagers and remote data loggers.

The absolute maximum ratings of the ICL7664 can be summarized as:(1)input supply voltage:-18 V;(2)input or output voltage terminals: (GND+0.3V) to (VIN-0.3V);(3)sense pin: (GND+0.3V) to (Vout-0.3V);(4)output sink current:-25 mA;(5)power dissipation minidip:200 mW;(6)power dissipation TO-99 can:300 mW;(7)power dissipation CERDIP:500 mW;(8)storage temperature: -65 to +150;(9)lead temperature (soldering, 10 seconds):+300.
