TK702xx

1.03 V REGULATOR WITH ON/OFF SWITCH

DESCRIPTION

The TK702xx is a very low dropout, low input voltage

operation regulator suitable for single battery cell applica-

tions. This regulator provides 1.03 V output with a dropout

voltage of only 30 mV. The active high control provides on/

off switching of the output. In the off mode, the standby

supply current is 8

µA, thus extending battery life.

The TK702xx is available in a very small plastic surface

mount package (SOT-25).
