DEFINITIONS

Dropout Voltage – The input/output voltage differential at

which the regulator output no longer maintains regulation

against further reductions in input voltage. Measured when

the output drops 100 mV below its nominal value (which is

measured at 1.0 V differential), dropout voltage is affected

by junction temperature, load current and minimum input

supply requirements.

Line Regulation – The change in output voltage for a change

in input voltage. The measurement is made under conditions

of low dissipation or by using pulse techniques such that

average chip temperature is not significantly affected.

Load Regulation – The change in output voltage for a

change in load current at constant chip temperature.

Maximum Power Dissipation – The maximum total device

dissipation for which the regulator will operate within

specifications.

Quiescent Bias Current – Current which is used to operate

the regulator chip and is not delivered to the load.

APPLICATIONS INFORMATION

Introduction

The MC78LC00 micropower voltage regulators are

specifically designed with high accuracy output voltage and

ultra low quiescent current by CMOS process making them

ideal for battery powered applications and hand–held

communication equipment. An input bypass capacitor is

recommended if the regulator is located an appreciable

distance (

≥

4 inches) from the input voltage source. These

regulators require

≥

0.1

F capacitance between the output

terminal and ground for stability. Most types of aluminum,

tantalum or multilayer ceramic will perform adequately. Solid

tantalums or other appropriate capacitors are recommended

for operation below 25

C. The bypass capacitors should be

mounted with the shortest possible leads or track lengths

directly across the regulator input and output terminals.

With economical electrolytic capacitors, cold temperature

operation can pose a serious stability problem. As the

electrolyte freezes, around –30

C, the capacitance will

decrease and the equivalent series resistance (ESR) will

increase drastically, causing the circuit to oscillate. Quality

electrolytic capacitors with extended temperature ranges of

–40

to +85

C are readily available. Solid tantalum

capacitors may be the better choice if small size is a

requirement. However, a maximum ESR limit of 3.0

Ω

must

be observed over temperature to maintain stability.

In the Current Boost Circuit, shown in Figures 10 and 12,

an output current of up to 600 mA can be delivered by the

circuit. The circuit of Figure 10 has no current limit. In each

case, the external transistor must be rated for the expected

power dissipation. Figure 11 shows how a fixed output may

be programmed, using R1 and R2, to provide a higher

output voltage.
