TK112xx
VOLTAGE REGULATOR WITH ON/OFF SWITCH
FEATURES
■ Low Dropout Voltage
■ CMOS/TTL Compatible ON/OFF Switch
■ Very Low Standby Current 180 µA (ON, No Load)
■ Internal Thermal Shutdown
■ Short Circuit Protection
■ Very Low (0.1 µA) Current in OFF Mode
■ Low Noise with External Bypass Capacitor
DESCRIPTION
The TK112XX is a low power, linear regulator with a builtin electronic switch. The internal electronic switch can be
controlled by TTL or CMOS logic levels. The device is in
the ON state when the control pin is pulled to a high logic
level. A pin for a bypass capacitor is provided, which
connects to the internal circuitry, to lower the overall output
noise level.
An internal PNP pass-transistor is used in order to achieve
low dropout voltage (typically 100 mV at 30 mA load
current). The device has very low quiescent current (180
µA) in the ON mode with no load and 1 mA with 30 mA load.
The quiescent current is typically 2.5 mA at 60 mA load.
When the device is in standby mode (V
quiescent current is typically 100 nA. An internal thermal
shutdown circuit limits the junction temperature to below
150 °C. The load current is internally monitored and the
device will shut down in the presence of a short circuit at the
output.
