General Description
The
(typically ±0.5%) CMOS upgrades for older (bipolar)
low dropout regulators such as the LP2980. Designed
specifically for battery-operated systems, the devices’
CMOS construction eliminates wasted ground current,
significantly extending battery life. Total supply current
is typically 50
μ
A at full load (20 to 60 times lower than
in bipolar regulators).
TC1014/TC1015/TC1185
are
high
accuracy
The devices’ key features include ultra low noise oper-
ation (plus optional Bypass input), fast response to step
changes in load, and very low dropout voltage –
typically 85mV (TC1014); 180mV (TC1015); and
270mV (TC1185) at full load. Supply current is reduced
to 0.5
μ
A (max) and V
OUT
falls to zero when the
shutdown input is low. The devices incorporate both
over-temperature and over-current protection.
The TC1014/TC1015/TC1185 are stable with an output
capacitor of only 1
μ
F and have a maximum output
current of 50mA, 100mA and 150mA, respectively. For
higher output current regulators, please see the
TC1107/TC1108/TC1173 (I
OUT
= 300mA) data sheets.
