AS1371
Datasheet - Detailed Description
8 Detailed Description
The AS1371 is a low-dropout, low-quiescent-current linear regulator intended for LDO regulator applications where
output current load requirements range from no load to 400mA. All devices come with fixed output voltage from 0.6V to
3.3V. (see Ordering Information on page 13).
The AS1371 also features a Power-OK output to indicate when the output is within 10% (max) of final value, and also
an Enable pin. Shutdown current for the whole regulator is typically 10nA. The device features integrated short-circuit
and over current protection. Under-Voltage lockout prevents erratic operation when the input voltage is slowly decaying
(e.g. in a battery powered application). Thermal Protection shuts down the device when die temperature reaches
150°C. This is a useful protection when the device is under sustained short circuit conditions.
As illustrated in Figure 13, the devices comprise voltage reference, error amplifier, P-channel MOSFET pass transistor,
Power-OK detect logic, internal voltage divider, current limiter, thermal sensor and shutdown logic.
The bandgap reference is connected to the inverting input of the error amplifier. The error amplifier compares this
reference with the feedback voltage and amplifies the difference. If the feedback voltage is lower than the reference
voltage, the P-channel MOSFET gate is pulled lower, allowing more current to pass to the output, and increases the
output voltage. If the feedback voltage is too high, the pass-transistor gate is pulled up, allowing less current to pass to
the output. The output voltage feeds back through an internal resistor voltage divider connected to pin OUT.

AS1371
Datasheet - Detailed Description
Power-OK and Low-Battery-Detect Functionality
The AS1371’s power-ok or low-battery-detect circuitry is built around an N-channel MOSFET. The circuitry monitors
the voltage on pin SENSE and if the voltage goes out of regulation (e.g. during dropout, current limit or thermal
shutdown) the pin POK goes low. The pin SENSE can be connected to a resistive-divider to monitor a particular
definable voltage and compare it with an internal voltage reference. If the SENSE pin is connected to GND an internal
resistive-divider is activated and connected to the output. Therefore, the Power-OK functionality can be realised with
no additional external components.
The Power-OK feature is not active during shutdown and provides a power-on-reset function that can operate down to
VIN = 1.2V. A capacitor to GND may be added to generate a power-on-reset delay. To obtain a logic-level output,
connect a pull-up resistor from pin POK to pin OUT. Larger values for this resistor will help to minimize current
consumption; a 100kΩ resistor is perfect for most applications (see Figure 1 on page 1).
For the circuit shown in the left of Figure 14 on page 11, the input bias current into SENSE is very low, permitting large-
value resistor-divider networks while maintaining accuracy. Place the resistor-divider network as close to the device as
possible. Use a defined resistor for R2 and then calculate R1 as:
VIN
⎛
⎝
⎞
– 1
------------------
R1 = R2 ×
(EQ 1)
⎠
VSENSE
Where:
VSENSE .... Is the internal sense reference voltage. For values see Table 3 on page 4.
R2 .... Is the predefined resistor in the resistor divider.
In case of the SENSE pin is connected to GND, an internal resistor-divider network is activated and compares the out-
put voltage with a 94% (typ.) voltage threshold. For this particular Power-OK application, no external resistive compo-
nents are necessary.
Current Limiting
The AS1371 include current limiting circuitry to protect against short-circuit conditions. The circuitry monitors and
controls the gate voltage of the P-channel MOSFET, limiting the output current to 400mA. The P-channel MOSFET
output can be shorted to ground for an indefinite period of time without damaging the device.
Thermal-Overload Protection
The devices are protected against thermal runaway conditions by the integrated thermal sensor circuitry. Thermal
shutdown is an effective instrument to prevent die overheating since the power transistor is the principle heat source in
the device.
If the junction temperature exceeds 150ºC with 15ºC hysteresis, the thermal sensor starts the shutdown logic, at which
point the P-channel MOSFET is switched off. After the device temperature has dropped by approximately 15ºC, the
thermal sensor will turn the P-channel MOSFET on again. Note that this will be exhibited as a pulsed output under
continuous thermal-overload conditions.
Note: The absolute maximum junction-temperature of +150ºC should not be exceeding during continual operation.

Operating Region and Power Dissipation
Maximum power dissipation is determined by the thermal resistance of the case and circuit board, the temperature
difference between the die junction and ambient air, and the rate of air flow. The power dissipation of the device is
calculated by:
P = IOUT × (VIN – VOUT
)
(EQ 2)
Maximum power dissipation is calculated by:
TJ – TAMB
------------------------

PMAX
(EQ 3)
θ

Where:
TJ - TAMB is the temperature difference between the device die junction and the surrounding air.
JB is the thermal resistance of the package.
JA is the thermal resistance through the circuit board, copper traces, and other materials to the surrounding.

θ
Note: Pin GND is a multi-function pin providing a connection to the system ground and acting as a heat sink. This pin
should be connected to the system ground using a large pad or a ground plane.

AS1371
Datasheet - Application Information
9 Application Information
Capacitor Selection and Regulator Stability
Ceramic capacitors are highly recommended as they offer distinct advantages over their tantalum and aluminum
electrolytic components. For stable operation with load currents up to 400mA over the entire device temperature
range, use a 1µF (min) ceramic output capacitor with an ESR <0.2Ω. Use large output capacitor values (e.g. 10µF) to
reduce noise and improve load transient-response, stability and power-supply rejection.
Note: Some ceramic capacitors exhibit large capacitance and ESR variations with variations in temperature.
Power Supply Rejection Ratio
The AS1371 is designed to deliver low dropout voltages and low quiescent currents. Power-supply rejection is typically
50dB at 10kHz. To improve power supply-noise rejection and transient response, increase the values of the input and
output bypass capacitors, which are shown in Figure 14.
The Section 6 Electrical Characteristics on page 4 show also the device line- and load-transient responses.
Dropout Voltage
For standard products with output voltage greater than the minimum VIN (1.2V), the minimum input-output voltage
differential (dropout voltage) determines the lowest usable supply voltage. This determines the useful end-of-life
battery voltage in battery-powered systems. The dropout voltage is a function of the P-MOSFET drain-to-source on-
resistance multiplied by the load current, and is calculated by:
VDROPOUT = VIN – VOUT = RDS(ON) × IOUT
(EQ 4)
Where:
RDS(ON) is the drain-to-source on -resistance.
IOUT is the output current.
