7 / 11 page 1.5A Very L.D.O Voltage Regulator LM27150/27151/27152 Dec. 2011 – Rev.1.3.1 - 7 - HTC Reference LM27152 VREF Reference Voltage 1.228 1.215 1.24 1.252 1.265 V (Note 6) 1.203 1.277 V IADJ Adjust Pin Bias Current 40 80 120 nA Reference Voltage Temp. Coefficient (Note 2) 20 ppm/℃ Adjust Pin Bias Current Temp. Coefficient 0.1 nA/℃ Enable Input LM27151 / LM27152 VEN Enable Input Voltage Logic Low (Off) Logic High (On) 2.4 0.8 V IEN Enable Pin Input Current VEN =26V 100 600 750 μA VEN =0.8V 2.5 5 μA Regulator Output Current Shutdown (Note 7) 10 500 μA Note 1. Employ pulse-testing procedures to minimize temperature rise Note 2. Output Voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range. Note 3. Dropout Voltage is defined as the input-to-output differential when the Output Voltage drops to 99% of its nominal value with V+1V applied to VOUTIN. For Output Voltages below 2.3V the Dropout Voltage is the input-to-output voltage differential with the minimum input voltage being 2.3V. The minimum input operation voltage is 2.3V. Note 4. GND pin current is the regulator quiescent current. The total current drawn from the source is a sum of the load current plus the GND pin current. Note 5. For specified VOUT ≥2.5V. Note 6. V≤VREFOUT≤(VIN-1V), 2.3V≤VIN≤26V, 10mA≤I≤1.5A, TLJ<TJ MAX. Note 7. VEN ≤0.8V and VIN ≤26V, V=0 Note 8. When used in dual supply systems, where the regulator load is returned to a negative supply, the output voltage must be diode- clamped to ground. |
