DESCRIPTION
TK70403 is a low dropout, linear regulator with a built-in electronic switch. A pin for a bypass capacitor is provided, which connects to the internal circuitry to lower the overall output noise level.

FEATURES
■ Low Input Voltage Operation (Single Battery Cell)
■ Internal PNP Transistor
■ Internal Shutdown Control (Off Current, 0.1 µA max)
■ Low Dropout Voltage [30 mV (typ.) at 2 mA]
■ Miniature Package (SOT-26)
■ Very Low Noise

APPLICATIONS
■ Pagers
■ Personal Communication Equipment
■ Portable Consumer Equipment
■ Radio Control Systems
■ Single Battery Cell Systems
