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
This integrated circuit can be damaged by ESD if you don’t pay attention to ESD protection. LINEARIN
recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper
handling and installation procedures can cause damage. ESD damage can range from subtle performance
degradation to complete device failure. Precision integrated circuits may be more susceptible to damage
because very small parametric changes could cause the device not to meet its published specifications.
LINEARIN reserves the right to make any change in circuit design, specification or other related things if
necessary without notice at any time. Please contact LINEARIN sales office to get the latest datasheet.

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.

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.
