LM2941 LM2941/LM2941C 1A Low Dropout Adjustable Regulator
FEATURES DESCRIPTION
The LM2941 positive voltage regulator features the 2• WSON Space Saving Package
ability to source 1A of output current with a typical
• Output Voltage Adjustable From 5V to 20V dropout voltage of 0.5V and a maximum of 1V over
• Dropout Voltage Typically 0.5V @ IO = 1A the entire temperature range. Furthermore, a
• Output Current in Excess of 1A quiescent current reduction circuit has been included
• Trimmed Reference Voltage which reduces the ground pin current when the differential between the input voltage and the output
• Reverse Battery Protection voltage exceeds approximately 3V. The quiescent
• Internal Short Circuit Current Limit current with 1A of output current and an input-output
• Mirror Image Insertion Protection differential of 5V is therefore only 30mA. Higher
quiescent currents only exist when the regulator is in
• P+ Product Enhancement Tested the dropout mode (VIN − VOUT ≤ 3V).
• TTL, CMOS Compatible ON/OFF Switch Designed also for vehicular applications, the LM2941
and all regulated circuitry are protected from reverse
battery installations or two-battery jumps. During line
transients, such as load dump when the input voltage
can momentarily exceed the specified maximum
operating voltage, the regulator will automatically shut
down to protect both the internal circuits and the load.
Familiar regulator features such as short circuit and
thermal overload protection are also provided.
