FN1620-2L.3 — Data Sheet 20 V Input Voltage, 1 A, High Speed LDOs LTP829 P-3 Block Diagram VIN VOUT Current Limit MOSFET Driver Thermal Shutdown RLOW Adaptive Bias VEN Band Gap FB Logic GND Functional Description Enable The LTP829 delivers the output power when it is set to enable state. When it works in disable state, there is no output power and the operation quiescent current is almost zero. The enable pin (EN) is active high. Shutdown Turn off the device by forcing the EN pin to drop below VEN(LO). If shutdown capability is not required, connect EN to IN. The LTP829 has an internal pulldown MOSFET that connects an RPULLDOWN resistor to ground when the device is disabled. The discharge time after disabling depends on the output capacitance (COUT) and the load resistance (RL) in parallel with the pulldown resistor (RPULLDOWN). Formula 1 calculates the time constant: τ = (RPULLDOWN × RL) / (RPULLDOWN + RL) (1) Over-Temperature Protection The over-temperature protection function will turn off the P-MOSFET when the junction temperature exceeds 150ºC (typical). Once the junction temperature cools down by approximately 20ºC the regulator will automatically resume operation. Current-Limit Protection The LTP829 provides current limit function to prevent the device from damages during over-load or shortedcircuit condition. This current is detected by an internal sensing transistor. CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.

FN1620-2L.3 — Data Sheet 20 V Input Voltage, 1 A, High Speed LDOs LTP829 P-11 Application Circuits VIN IN VOUT OUT R1 CIN EN GND FB COUT R2 Functional Description Input and Output Capacitor Selection The LTP829 requires an output capacitance of 1μF or larger for stability. Use X5R-type and X7R-type ceramic capacitors because these capacitors have minimal variation in value and equivalent series resistance (ESR) over temperature. When choosing a capacitor for a specific application, pay attention to the DC bias characteristics for the capacitor. Higher output voltages cause a significant derating of the capacitor. Although an input capacitor is not required for stability, good analog design practice is to connect a capacitor from IN to GND. Some input supplies have a high impedance, thus placing the input capacitor on the input supply helps reduce the input impedance. This capacitor counteracts reactive input sources and improves transient response, input ripple, and PSRR. If the input supply has a high impedance over a large range of frequencies, several input capacitors can be used in parallel to lower the impedance over frequency. Use a higher-value capacitor if large, fast, rise-time load transients are anticipated, or if the device is located several inches from the input power source. Application of Electrolytic Capacitor If the electrolytic capacitor should be used as input and output capacitor, the capacitance of the capacitor must be greater. Enable The LTP829 has an EN pin to turn on or turn off the regulator, When the EN pin is in logic high, the regulator will be turned on. The shutdown current is almost 0μA typical. The EN pin may be directly tied to VIN to keep the part on. The Enable input is CMOS logic and cannot be left floating. Setting the Output Voltage The LTP829 develops a 0.64 V reference voltage, VFB, between the output and the adjust terminal. This voltage is applied across resistor R1 to generate a constant current. The current IADJ from the ADJ terminal could introduce DC offset to the output. Because, this offset is very small (about 0.1 μA) , it can be ignored. The constant current then flows through the output set resistor R2 and sets the output voltage to the desired level. Equation 2 is used for calculating VOUT: VOUT = VFB × (1 + R1/R2) (2) Although IADJ is very small, R1 + R2 should be limited to less than 100kΩ for optimum performance. Dropout Voltage The LTP829 uses a PMOS pass transistor to achieve low dropout. When (VIN - VOUT) is less than the dropout voltage (VDO), the PMOS pass device is in the linear region of operation and the input-to-output resistance is the RDS(ON) of the PMOS pass element. VDO scales approximately with output current because the PMOS device behaves like a resistor in dropout mode. As with any linear regulator, PSRR and transient response degrade as (VIN - VOUT) approaches dropout operation.

FN1620-2L.3 — Data Sheet 20 V Input Voltage, 1 A, High Speed LDOs P-12 LTP829 Functional Description Thermal Shutdown Thermal shutdown protection disables the output when the junction temperature rises to approximately 150ºC Disabling the device eliminates the power dissipated by the device, allowing the device to cool. When the junction temperature cools to approximately 125ºC, the output circuitry is again enabled. Depending on power dissipation, thermal resistance, and ambient temperature, the thermal protection circuit may cycle on and off. This cycling limits regulator dissipation, protecting the LDO from damage as a result of overheating. Activating the thermal shutdown feature usually indicates excessive power dissipation as a result of the product of the (VIN - VOUT) voltage and the load current. For reliable operation, limit junction temperature to 125ºC maximum. Thermal Considerations For continuous operation, do not exceed absolute maximum junction temperature. The maximum power dissipation depends on the thermal resistance of the IC package, PCB layout, rate of surrounding airflow, and difference between junction and ambient temperature. The maximum power dissipation can be calculated by the following formula : PD(MAX) = (TJ(MAX) - TA) / θJA where TJ(MAX) is the maximum junction temperature, TA is the ambient temperature, and θJA is the junction to ambient thermal resistance. For recommended operating condition specifications the maximum junction temperature is 125ºC and TA is the ambient temperature. The junction to ambient thermal resistance, θJA, is layout dependent. The maximum power dissipation depends on the operating ambient temperature for fixed TJ(MAX) and thermal resistance, θJA.
