Overview
The Panasonic AN8003M-E1 is a 3-pin, positive output, low dropout voltage regulator from the AN80xxM series. It provides a fixed 3V output with a maximum input/output voltage difference of 0.3V and supports an output current of up to 50mA. The device features a typical bias current of 0.6mA and includes built-in overcurrent protection. Electrical characteristics at Ta = 25°C specify a minimum output voltage of 2.88V, a line regulation of 30mV (VI = 3.5 to 9V), and a load regulation of 25mV (IO = 1 to 40mA). The ripple rejection ratio is typically 58dB at 120Hz.
Feature Summary
- Low dropout operation with minimal input-to-output voltage differential
- Integrated overcurrent protection circuit for internal safeguarding
- Optimized for battery-powered applications due to low power consumption
Applications
- Battery-powered power supply circuits
- Reference voltage generation in electronic systems
- Low dropout linear regulation for portable devices
Procurement Notes
Verify the specific suffix E1 against official Panasonic documentation to confirm packaging or tape-and-reel specifications. Ensure compatibility with standard board mounting requirements for thermal dissipation. Confirm that the HSIP003-P-0000B package dimensions align with the target PCB layout before finalizing procurement orders.
Selection Notes
Select this component when a fixed 3V output is required with minimal voltage headroom. The AN8003M variant offers improved performance through increased internal gain compared to the standard AN8003 series. Consider the 50mA current limit and thermal constraints when designing for high ambient temperatures or long output traces requiring additional capacitance.
Part Context
The AN8003M-E1 belongs to the AN80xxM series of monolithic voltage regulators manufactured by Panasonic Electronic Components. This series is designed as a 3-pin, positive output, low dropout regulator optimized for minimizing power consumption. The 'M' designation indicates enhanced performance characteristics relative to the base AN80xx series.
Replacement Considerations
The datasheet identifies the AN8003 as the corresponding non-M series part. No other specific substitute part numbers are documented in the provided source material.
