DESCRIPTION

The TK716xx is a low dropout linear regulator housed in a small SOT23-5 package, rated at 500 mW. The phase compensation in the IC has been optimized to allow the use of ceramic or tantalum output capacitors. The device is in the “on” state when the control pin is pulled to a logic high level. An internal PNP pass transistor is used to achieve a low dropout voltage of 90 mV (typ.) at 50 mA load current. This device offers high precision output voltage of ± 2.0 % or ± 1.0 %. The low quiescent current and dropout voltage make this part ideal for battery powered applications. This part incorporates an output disconnect feature to reduce the reverse bias current in the “off” state to less than 50 nA.

CAPACITOR CODE

for availability.

A: Tantalum Capacitor

The internal reverse bias protection eliminates the requirement for a reverse voltage protection diode, saving cost and board space. The high 60 dB ripple rejection (400 Hz) and low noise provide enhanced performance for critical applications. An external capacitor can be connected to the noise bypass pin to lower the output noise level to 30Vrms.
