400mA and 500mA Voltage Regulators
General Description

The LM2937-2.5and LM2937-3.3are positive voltage regu-
lators capableof supplyingupto 500mAof load current.
Both regulatorsare idealfor convertinga common5V logic
supply,or higher input supply voltage,tothe lower 2.5Vand
3.3V suppliesto power VLSI ASIC’s and microcontrollers.
Special circuitryhas been incorporatedto minimizethequi-
escent currentto typicallyonly10mAwithafull500mA load
current whenthe inputto output voltagedifferentialis greater
than5V.
The LM2937 requiresan output bypass capacitorfor stabil-
ity.As with most regulators utilizinga PNP pass transistor,
the ESRofthis capacitor remainsa critical design param-
eter,butthe LM2937-2.5 and LM2937-3.3 include special
compensation circuitry that relaxes ESR requirements.The
LM2937is stableforall ESR ratings less than5Ω. Thisal-
lowstheuseoflow ESR chip capacitors.
The regulatorsare also suitedfor automotive applications,
with builtin protection from reverse battery connections,
two-battery jumps andupto +60V/−50V load dump tran-
sients. Familiar regulator features suchas short circuit and
thermal shutdown protectionare also builtin.
Features

SOT-223 package) Output trimmedfor5% tolerance underall operating
conditions Wide output capacitor ESR range, 0.01Ωupto5Ω Internal short circuitand thermal overload protection Reverse battery protection 60V input transient protection Mirror image insertion protection
