200mA CMOS LDO Regulator
TK681xxAMF/M5/S2
1. DESCRIPTION
The TK681xxAMF/M5/S2 is a CMOS LDO regulator.
The package is the very small and thin HSON1214-4, the
small and thin SON2017-6, and the small and versatile
SOT23-5.
The IC is designed for portable applications with space
requirements.
The IC can supply 200mA output current.
The IC offers low quiescent current.
The IC does not require a noise-bypass capacitor.
The output voltage is internally fixed from 1.2V to 4.2V.

The maximum output current is limited by power dissipation.
The maximum load current is the current where the output voltage decreases to 90% by increasing the output current at
T

=25°C, compared to the output voltage specified at V

+1V. The maximum load current indicates the current
at which over current protection turn on.
For all output voltage products, the maximum output current for normal operation without operating any protection is
200mA. Accordingly, LoaReg and V
Drop
are specified on the condition that I
Out
is less than 200mA.
General Note
Parameters with only typical values are just reference. (Not guaranteed)
The noise level is dependent on the output voltage, the capacitance and capacitor characteristics.
