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 pow-
ered applications. This part incorporates an output discon-
nect feature to reduce the reverse bias current in the “off”
state to less than 50 nA.

LOW DROPOUT VOLTAGE REGULATOR
The internal reverse bias protection eliminates the require-
ment 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 30
μ
Vrms.
