TK701xx
1.0 V LOW DROPOUT LINEAR REGULATOR
FEATURES
■ Low Input Voltage Operation (Single Battery Cell)
■ Internal PNP Transistor
■ Built-In Shutdown Control (Off Current, 10 µ A Typ)
■ Low Dropout Voltage (30 mV Typ)
■ High Speed ON/OFF Transient, (15 µs Typ)
■ Very Small Surface Mount Package (SOT-25)
DESCRIPTION
The TK701xx is a very low dropout, low input voltage
operation regulator suitable for single battery cell applications. This regulator provides 1.0 V output with a dropout
voltage of only 30 mV. The active low control provides on/
off switching of the output. In the off mode, the standby
supply current is 10 µA, thus extending battery life.
The TK701xx is available in a very small plastic surface
mount package (SOT-25).
APPLICATIONS
■ Pagers
■ Personal Communication Equipment
■ Portable Consumer Equipment
■ Radio Control Systems
■ Single Battery Cell Systems
