mic47100 Micrel Semiconductor, mic47100 Datasheet - Page 5

• Manufacturer Part Number: mic47100
• Description: Mic47100 1a High Speed Low Vin Ldo
• Manufacturer: Micrel Semiconductor

Notes:
1. Exceeding the absolute maximum rating may damage the device.
2. The device is not guaranteed to function outside its operating rating.
3. The maximum allowable power dissipation of any T
dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown.
4. Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5kΩ in series with 100pF.
5. Specification for packaged product only.
6. Both UVLO thresholds must be met for the output voltage to be allowed to turn-on. If either of the two input voltages are below the UVLO thresholds,
the output is kept off.
