LM2930 3-Terminal Positive Regulator

Check for Samples: LM2930

FEATURES

DESCRIPTION

The LM2930 3-terminal positive regulator features an

• Input-Output Differential Less Than 0.6V

ability to source 150 mA of output current with an

• Output Current in Excess of 150 mA

input-output differential of 0.6V or less. Efficient use

• Reverse Battery Protection

of low input voltages obtained, for example, from an

automotive battery during cold crank conditions,

• 40V Load Dump Protection

allows 5V circuitry to be properly powered with supply

• Internal Short Circuit Current Limit

voltages as low as 5.6V. Familiar regulator features

• Internal Thermal Overload Protection

such as current limit and thermal overload protection

are also provided.

• Mirror-Image Insertion Protection

• P

Product Enhancement Tested

Designed originally for automotive applications, the

LM2930 and all regulated circuitry are protected from

reverse battery installations or 2 battery jumps.

VOLTAGE RANGE

During line transients, such as a load dump (40V)

• LM2930T-5.0: 5V

when the input voltage to the regulator can

• LM2930T-8.0: 8V

momentarily exceed the specified maximum

operating voltage, the regulator will automatically shut

• LM2930S-5.0: 5V

down to protect both internal circuits and the load.

• LM2930S-8.0: 8V

The LM2930 cannot be harmed by temporary mirror-

image insertion.

Fixed outputs of 5V and 8V are available in the

plastic TO-220 and SFM power packages.

LM2930 www.ti.com SNVS745D – APRIL 1998 – REVISED APRIL 2013 Definition of Terms Dropout Voltage: The input-output voltage differential at which the circuit ceases to regulate against further reduction in input voltage. Measured when the output voltage has dropped 100 mV from the nominal value obtained at 14V input, dropout voltage is dependent upon load current and junction temperature. Input Voltage: The DC voltage applied to the input terminals with respect to ground.
