General Description
The TC1107 is a fixed output, high accuracy (typically
±0.5%) CMOS upgrade for older (bipolar) low dropout
regulators. Total supply current is typically 50µA at full
load (20 to 60 times lower than in bipolar regulators).
TC1107 key features include ultra low noise operation
(plus optional Bypass input); very low dropout voltage
(typically 240mV at full load), and fast response to step
changes in load. Supply current is reduced to 0.05µA
(typical) and VOUT falls to zero when the shutdown
input is low.
The TC1107 incorporates both over temperature and
over current protection. The TC1107 is stable with an
output capacitor of only 1µF and has a maximum
output current of 300mA.

1: VR is the regulator output voltage setting.
2: TC VOUT = (VOUTMAX – VOUTMIN) x 106
VOUT x T
3: Regulation is measured at a constant junction temperature using low duty cycle pulse testing. Load regulation is tested over a load range
from 0.1mA to the maximum specified output current. Changes in output voltage due to heating effects are covered by the thermal
regulation specification.
4: Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value measured at a
1V differential.
5: Thermal Regulation is defined as the change in output voltage at a time T after a change in power dissipation is applied, excluding load or
line regulation effects. Specifications are for a current pulse equal to ILMAX at VIN = 6V for T = 10 msec.
6: The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable junction temperature and the
thermal resistance from junction-to-air (i.e., TA, TJ, θJA). Exceeding the maximum allowable power dissipation causes the device to initiate
thermal shutdown. Please see Section 4.0 Thermal Considerations for more details.
7: The minimum VIN has to justify the conditions: VIN VR + VDROPOUT and VIN 2.7V for IL = 0.1mA to IOUTMAX.
