LM9076Q 150mA Ultra-Low Quiescent Current LDO Regulator with Delayed Reset Output Literature Number: SNVS713A

November 16, 2011 150mA Ultra-Low Quiescent Current LDO Regulator with Delayed Reset Output General Description The LM9076Q is a ±3%, 150 mA logic controlled voltage reg- ulator. The regulator features an active low delayed reset output flag which can be used to reset a microprocessor sys- tem at turn-ON and in the event that the regulator output voltage falls below a minimum value. An external capacitor programs a delay time interval before the reset output pin can return high. Designed for automotive and industrial applications, the LM9076Q contains a variety of protection features such as thermal shutdown, input transient protection and a wide op- erating temperature range. The LM9076Q uses an PNP pass transistor which allows low drop-out voltage operation.

Minimum, Typical, and/or Maximum values are provided for informational purposes only. Note 4: Pulse testing used maintain constant junction temperature (TJ ). Note 5: The regulated output voltage specification is not guaranteed for the entire range of VIN and output loads. Device operational range is limited by the maximum junction temperature (T J ). The junction temperature is influenced by the ambient temperature (T A ), package selection, input voltage (VIN ), and the output load current. When operating with maximum load currents the input voltage and/or ambient temperature will be limited. When operating with maximum input voltage the load current and/or the ambient temperature will be limited. Note 6: Worst case (FREE AIR) per EIA/JESD51–3. www.ti.com 6 LM9076Q

Application Information

The LM9076Q regulator is suitable for Automotive and Indus- trial applications where continuous connection to a battery supply is required (refer to the Typical Application circuit). The pass element of the regulator is a PNP device which re- quires an output bypass capacitor for stability. The minimum bypass capacitance for the output is 10 μF (refer to ESR lim- itations). A 22 μF, or larger, output bypass capacitor is rec- ommended for typical applications INPUT CAPACITOR The LM9076Q requires a low source impedance to maintain regulator stability because critical portions of the internal bias circuitry are connected to directly to V IN. In general, a 10 μF electrolytic capacitor, located within two inches of the LM9076Q, is adequate for a majority of applications. Addi- tionally, and at a minimum, a 0.1 μF ceramic capacitor should be located between the LM9076Q V IN and Ground pin, and as close as is physically possible to the LM9076Q itself . OUTPUT CAPACITOR An output bypass capacitor is required for stability. This ca- pacitance must be placed between the LM9076Q V OUT pin and Ground pin, as close as is physically possible, using traces that are not part of the load current path. The output capacitor must meet the requirements for mini- mum capacitance and also maintain the appropriate ESR value across the entire operating ambient temperature range. There is no limit to the maximum output capacitance as long as ESR is maintained. The minimum bypass capacitance for the output is 10 μF (re- fer to ESR limitations). A 22 μF, or larger, output bypass capacitor is recommended for typical applications. Solid tantalums capacitors are recommended as they gener- ally maintain capacitance and ESR ratings over a wide tem- perature range. Ceramic capacitor types XR7 and XR5 may be used if a series resistor is added to simulate the minimum ESR requirement. See Figure 1. Aluminum electrolytic capacitors are not recommended as they are subject to wide changes in capacitance and ESR across temperature. 30154348 FIGURE 1.
