Output Current in Excess of 1A
Dropout Voltage Typically 0.6V at 1A Load
Low Quiescent Current
Internal Short Circuit Current Limit
Internal Thermal Shutdown with Hysteresis
TTL, CMOS Compatible ON/OFF Switch
Functional Complement to the LM2941 Series APPLICATIONS Post Switcher Regulator
Local, On-card, Regulation
Battery Operated Equipment The LM2991 is a low dropout adjustable negative
regulator with a output voltage range between -2V to
-25V. The LM2991 provides up to 1A of load current
and features a On /Off pin for remote shutdown
capability.
The LM2991 uses new circuit design techniques to
provide a low dropout voltage, low quiescent current
and low temperature coefficient precision reference.
The dropout voltage at 1A load current is typically
0.6V and a ensured worst-case maximum of 1V over
the entire operating temperature range. The
quiescent current is typically 1 mA with a 1A load …
