Micropower Voltage Regulators for Portable Applications
Micropower smallCAP
MC33264D, DM
T A = –40 to +85 C, Case 751, 846A
regulators available in SO–8 and Micro–8 surface mount
packages and a wide range of output voltages. These de-
vices feature a very low quiescent current (100 A in the ON
mode; 0.1 A in the OFF mode), and are capable of supply-
ing output currents up to 100 mA. Internal current and ther-
mal limiting protection is provided. They require only a small
output capacitance for stability.
tive LOW control (Pins 2 and 3) that allows a logic level signal
to turn–off or turn–on the regulator output.
bias current specifications, these devices are ideally suited
for battery powered computer, consumer, and industrial
equipment where an extension of useful battery life is desir-
able.
