Aug. 2020 – R1.1 8/12 HTC 150mA Ultra-Low IQ LDO Voltage Regulator LM9076 APPLICATION INFORMATION REGULATOR BASICS The LM9076 regulator is suitable for Automotive and Industrial applications where continuous connection to a battery supply is required (refer to Typical Application Circuits). The pass element of the regulator is a PNP device which requires an output bypass capacitor for stability. The minimum bypass capacitance for the output is 10µF (refer to ESR limitations). A 22µF or larger, output bypass capacitor is recommended for typical applications. INPUT CAPACITOR The LM9076 requires a low source impedance to maintain regulator stability because critical portions of the internal bias circuitry are connected to directly to IN pin. In general, a 10µF electrolytic capacitor, located within two inches of the LM9076, is adequate for a majority of applications. Additionally, and at a minimum, a 0.1µF ceramic capacitor should be located between the LM9076 IN pin and GND pin, and as close as is physically possible to the LM9076 itself. OUTPUT CAPACITOR An output bypass capacitor is required for stability. This capacitance must be placed between the LM9076 OUT pin and GND 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 minimum 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 10µF (refer to ESR limitations). A 22µF, or larger, output bypass capacitor is recommended for typical applications. Solid tantalums capacitors are recommended as they generally maintain capacitance and ESR ratings over a wide temperature range. Ceramic capacitor types XR7 and XR5 may be used if a series resistor is added to simulate the minimum ESR requirement. Unregulated DC Input Regulated Output IN OUT LM9076 10µF 0.1µF COUT 22µF CERAMIC GND REQUIV-ESR 1.0Ω Aluminum electrolytic capacitors are not recommended as they are subject to wide changes in capacitance and ESR across temperature. DELAY CAPACITOR The capacitor on the DELAY pin must be a low leakage type since the charge current is minimal (420nA typical) and the pin must fully charge to VOUT. Ceramic, Mylar, and polystyrene capacitor types are generally recommended, although changes in capacitance values across temperature changes will have some effect on the delay timing. Aug. 2020 – R1.1 9/12 HTC 150mA Ultra-Low IQ LDO Voltage Regulator LM9076 Any leakage of the IDELAY current, be it through the delay capacitor or any other path, will extend the delay time, possibly to the point that the RESET pin output does not go high. SHUTDOWN PIN (LM9076D ONLY) The basic On/Off control of the regulator is accomplished with the SHUTDOWN pin. By pulling the SHUTDOWN pin high the regulator output is switched off. When the regulator is switched off the load on the battery will be primarily due to the SHUTDOWN pin current. When the SHUTDOWN pin is low, or left open, the regulator is switched on. When an unregulated supply, such as V BATTERY, is used to pull the SHUTDOWN pin high a series resistor in the range of 10kΩ to 50kΩ is recommended to provide reverse voltage transient protection of the SHUTDOWN pin. Adding a small capacitor (0.001µF typical) from the SHUTDOWN pin to GND will add noise immunity to prevent accidental turn on due to noise on the supply line. RESET FLAG The RESET pin is and is an open collector output which requires an external pull-up resistor to develop the reset signal. The external pull-up resistor should be in the range of 10kΩ to 200kΩ. At VIN values of less than typically 2V the RESET pin voltage will be high. For VIN values between typically 2V and approximately VOUT + VBE the RESET pin voltage will be low. For VIN values greater than approximately VOUT + VBE the RESET pin voltage will be dependent on the status of the OUT pin voltage and the Delayed Reset circuitry. The value of VBE is typically 600mV at 25°C and will decrease approximately 2mV for every 1°C increase in the junction temperature. During normal operation the RESET pin voltage will be high. Any load condition that causes the OUT pin voltage to drop below typically 89% of normal will activate the Delayed Reset circuit and the RESET pin will go low for the duration of the delay time. Any line condition that causes IN pin voltage to drop below typically VOUT + VBE will cause the RESET pin to go low without activating the Delayed Reset circuitry. Excessive thermal dissipation will raise the junction temperature and could activate the Thermal Shutdown circuitry which, in turn, will cause the RESET pin to go low. For the LM9076D, pulling the SHUTDOWN pin high will turn off the output which, in turn, will cause the RESET pin to go low once the VOUT voltage has decayed to a value that is less than typically 89% of normal. +50V VIN +14V VOUT + VBE 0V VOUT(NOM) VOUT 89% Load Transient 0V VOH VRESET 0V Delayed Reset Aug. 2020 – R1.1 Delayed Reset 10/12 Delayed Reset HTC 150mA Ultra-Low IQ LDO Voltage Regulator LM9076 RESET DELAY TIME When the regulator output is switched on, or after recovery from brief VOUT fault condition, the RESET flag can be programmed to remain low for an additional delay time. This will give time for any system reference voltages, clock signals, etc., to stabilize before the micro-controller resumes normal operation. This delay time is controlled by the capacitor value on the DELAY pin. During normal operation the DELAY capacitor is charged to near VOUT. When a VOUT fault is removed, the VOUT returns to the normal operating value, the DELAY capacitor begins charging at a typical constant 0.420µA rate. When the voltage on the DELAY capacitor reaches the same potential as the OUT pin the RESET pin will be allowed to return high. The typical RESET delay time can be calculated with following formula: tDELAY = VOUT × (CDELAY / IDELAY) (1) For the LM9076-3.3 with a CDELAY value of 0.001µF and a IDELAY of 0.420µA the typical RESET delay time is: tDELAY = 3.3V × (0.001µF / 0.420µA) = 7.8ms (2) For the LM9076-5.0 with a CDELAY value of 0.001µF and a IDELAY value of 0.420µA the typical RESET delay time is: tDELAY = 5.0V × (0.001µF / 0.420µA) = 11.9ms (3) THERMAL PROTECTION Device operational range is limited by the maximum junction temperature (TJ). The junction temperature is influenced by the ambient temperature (TA), 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. Even though the LM9076 is equipped with circuitry to protect itself from excessive thermal dissipation, it is not recommended that the LM9076 be operated at, or near, the maximum recommended die junction temperature (T J) as this may impair long term device reliability. The thermal protection circuitry monitors the temperature at the die level. When the die temperature exceeds typically 160°C the voltage regulator output will be switched off.
