LM78L00
1. Overview
1.1
Description
LM78L00 a series of positive voltage regulators are inexpensive,
easy-to-use devices suitable for a multitude of applications that require a regulated supply of up to 100 mA.
These devices offer a substantial performance advantage over the traditional Zener Diode–Resistor
combination, as output impedance and quiescent current are substantially reduced.
1.2
Features
• Low Cost
• No external components required
• Output voltages (5V, 6V, 8V, 9V, 10V, 12V, 15V, 18V, 24V)
• Internal Thermal shutdown and SOA protection
• Output voltage offered in
4% Tolerance
• Pb-Free Packages are available
• High ESD Level (HBM>8,000V, MM>800V)

The input voltage must remain typically 2.0V above the output voltage even during the
Low point on the ripple voltage.
• C

is required if regulator is located an appreciable distance from power filter.
• Co improves transient response. Value of
