Typical Application

General Description:

The TC1070, TC1071 and TC1187 are adjustable

LDOs designed to supersede a variety of older (bipolar)

voltage regulators. Total supply current is typically

50

μA at full load (20 to 60 times lower than in bipolar

regulators).

The devices’ key features include ultra low-noise

operation, very low dropout voltage – typically 85 mV

(TC1070); 180 mV (TC1071); and 270 mV (TC1187) at

full load, and fast response to step changes in load.

Supply current is reduced to 0.5

μA (maximum) when

the shutdown input is low. The devices incorporate both

over-temperature and over-current protection. Output

voltage is programmed with a simple resistor divider

from VOUT to ADJ to GND.

The TC1070, TC1071 and TC1187 are stable with an

output capacitor of only 1

μF and have a maximum

output current of 50 mA, 100 mA and 150 mA,

respectively. For higher output versions, please see the

TC1174 (IOUT = 300 mA) data sheet.
