Operating quiescent current is 500μA, reducing to less than 1μA in shutdown. Output voltage ranges from 1.2V to 19.5V. A small 10µF capacitor on the output with an ESR of less than 1Ω is adequate to ensure stability. Applications with large output load transients require a larger output capacitor value to minimize output voltage change. Input circuitry ensures output safe operating area with current limiting and thermal shutdown protection. The rated dropout of an RH1965-based part is dependent on the internal bond wire length/resistance. Linear Technology dice element evaluations are based on parts rated for 0.9A output current that are assembled in 4-Lead TO-3 can packages. nn nn L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear Technology Corporation.

Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: Absolute maximum input to output differential voltage is not achievable with all combinations of rated IN pin and OUT pin voltages. With the IN pin at 22V, the OUT pin may not be pulled below 0V. The total measured voltage from IN to OUT must not exceed ±22V. Note 3: The RH1965MK DICE is tested and specified under pulse load conditions such that TJ ≅ TA. Note 4: The RH1965MK DICE is tested and specified for these conditions with the ADJ pin connected to the output. 1.5 0.37 1.5 0.37 1.5 0.37 1.5 0.37 1 1 1 1 1 mA 400 400 400 400 400 μA Note 5: Maximum junction temperature limits operating conditions. The regulated output voltage specification does not apply for all possible combinations of input voltage and output current. Limit the output current range if operating at the maximum input voltage. Limit the input-to-output voltage differential if operating at the maximum output current. Note 6: To satisfy minimum input voltage requirements, the RH1965MK DICE is tested and specified for these conditions with an external resistor divider (bottom 4.02k, top 4.32k) for an output voltage of 2.5V. The external resistor divider adds 300μA of output DC load current. This external current is not factored into GND pin current. Note 7: Dropout voltage is the minimum input-to-output voltage differential needed to maintain regulation at a specified output current. In dropout, the output voltage equals: (VIN – VDROPOUT). rh1965mkf 4 For more information www.linear.com/RH1965MK RH1965MK DICE/DWF Electrical characteristics Note 8: GND pin current is tested with VIN = VOUT(NOMINAL) + 1V and a current source load. GND pin current increases slightly in dropout. Note 9: ADJ pin bias current flows into the ADJ pin. Note 10: SHDN pin current flows into the SHDN pin. Note 11: Reverse-output current is tested with the IN pin grounded and the OUT pin forced to 1.2V. This current flows into the OUT pin and out of the GND pin. Note 12: The minimum input voltage specification limits the dropout voltage under some output voltage/load conditions Note 13: This IC includes overtemperature protection that is intended to protect the device during momentary overload conditions. Junction temperature exceeds the maximum junction temperature when overtemperature protection is active. Continuous operation above the specified maximum operating junction temperature may impair device reliability. Note 14: Dice are probe tested at 25°C to the limits shown in Table 1. Except for high current tests, dice are tested under low current conditions which assure full load current specifications when assembled. Note 15: Dice that are not qualified by Linear Technology with a can sample are guaranteed to meet specifications of Table 1 only. Dice qualified by Linear Technology with a can sample meet specifications in all tables.
