Notes:
1. Exceeding the absolute maximum rating may damage the device.
2. The device is not guaranteed to function outside its operating rating.
3. Devices are ESD sensitive. Handling precautions recommended.
4. PD(max) = (TJ(max) â TA) ÷ θJA, where θJA depends upon the printed circuit layout. See âApplications Information.â
5. Specification for packaged product only.
6. Output voltage temperature coefficient is âVOUT(worst case) ÷ (TJ(max) â TJ(min)) where T J(max) is +125°C and TJ(min) is â40°C.
7. VDO = VIN â VOUT when VOUT decreases to 98% of its nominal output voltage with VIN = VOUT + 1V. For output voltages below 2.25V, dropout voltage is
the input-to-output voltage differential with the minimum input voltage being 2.25V. Minimum input operating voltage is 2.25V.
8. IGND is the quiescent current. IIN = IGND + IOUT.
9. VEN ⤠0.8V, VIN ⤠8V, and VOUT = 0V.
10. For a 2.5V device, VIN = 2.250V (device is in dropout).
11. Thermal regulation is deï¬ned as the change in output voltage at a time t after a change in power dissipation is applied, excluding load or line
regulation effects. Speciï¬cations are for a 200mA load pulse at VIN = 8V for t = 10ms.
