Features
en
AW37030YXXX integrates current limit, short circuit
protection, thermal shutdown, sufficiently protecting
IC from being damaged.
AW37030YXXX is designed to work with a 1F or
more input ceramic capacitor and a 1F or more
output ceramic capacitor. The low power dissipation
and good dynamic response make AW37030YXXX
very suitable for hand-held communication
equipment. Tiny package makes high density
mounting of the IC on boards possible.
(IOUT=300mA, 1.8V output)
Power supply rejection ratio: typical 90dB
(IOUT=30mA, freq=1kHz, 1.8V output)
⚫
Noise: typical 33Vrms (IOUT=30mA, BW=10Hz
to 100kHz, 1.8V output)
⚫
Built-in output short protection: typical 120mA
when output short to ground

Detailed Functional Description
tia
l
AW37030YXXX is a low dropout voltage regulator. After powered on, with CE pin assertion, feedback voltage
signal from the integrated resistor network and a voltage related to the voltage reference are transmit to positive
input terminal and negative input terminal of an error amplifier (EA) respectively. The output signal of EA is
used to control the open-state of power MOSFET. After soft-start, feedback voltage signal compares with the
established reference voltage, making output voltage stable and accurate. AW37030YXXX integrates function
of load transient accelerating, making LDO obtain excellent dynamic load transient response performance.
Enable Operation
AW37030YXXX uses CE pin to realize enable operation. Applying proper value of voltage to CE pin can make
IC enable/disable.
en
If the voltage of CE pin is less than 0.4V, AW37030YXXX is guaranteed to be disabled. In this state, function
modules of IC and power MOSFET are turned off. And the auto discharge function is enabled making output
discharge through a on-state NMOSFET to Ground. In disable state, AW37030YXXX only consumes a typical
10nA current.
fid
If the voltage of CE pin is more than 1V, AW37030YXXX is guaranteed to be enabled. In this state, the auto
discharge function is disabled, and AW37030YXXX regulates output voltage to the designed value of voltage.
on
A 140nA pull down current to Ground is built-in at CE pin, making sure that the IC is disabled when CE pin
floats. If Enable function is not required, CE pin should be connected directly to IN pin.
Output Current Limit
AW37030YXXX integrates output current limit function, protecting IC from excessive current.
cC
When the load is excessively heavy, AW37030YXXX limits the current flowing through the IC to a typical 500mA
current. This value is specially designed, so that IC is protected properly and the output capability of 300mA is
not influenced either.
aw
ini
Meanwhile, AW37030YXXX integrates a 120mA fold-back current limit function, lowering the system
dissipation when output overload or short to Ground.
Thermal Shutdown
AW37030YXXX integrates thermal shutdown function, protect IC from excessively high temperature.
When the chip temperature exceeds 160°C, AW37030YXXX detects it as an over-temperature event, triggering
thermal shutdown, which will turn off the main function module, including power MOSFET. This inhibits increase
of chip’s temperature. IC would keep the protection-state on until the chip’s temperature falls below to 130°C.
At this moment, the over-temperature protection-state is released, IC resumes to work again.The hysteresis
avoids IC’s turning off and on frequently around the the Thermal Shutdown threshold.
Auto Discharge
AW37030YXXX makes output voltage discharge quickly when in CE disable state or thermal shutdown state,
benefit from integrating auto discharge function. Auto discharge function is implemented by integrated a
NMOSFET of typical 130Ω Rdson route from Output to Ground, and the route is get through in CE disable
state or thermal shutdown state. This feature prevents residual charge voltage on the output capacitor, which
may impact proper power up of the system connected to the converter. It should be noted that auto discharge
function is optional according to different specs.

Application Information
Power Dissipation and Device Operation
The permissible power dissipation is dependent on the ambient temperature TA and the junction-to-ambient
thermal resistance RθJA.
l
The absolute maximum allowable power dissipation for the device in a given package can be calculated using
Equation below, where TJ_MAX = 150°C :
tia
PDMAX_ABS = (TJ_MAX – TA) / RθJA
The recommended maximum allowable power dissipation for the device in a given package can be calculated
using Equation below, where TJ_REC = 125°C :
PDMAX_REC = (TJ_REC – TA) / RθJA
en
The actual power being dissipated in the device can be represented by Equation below:
PDACT = (VIN – VOUT) × IOUT
fid
These equations above establish the relationship between the maximum power dissipation allowed due to
thermal consideration, the voltage drop across the device, and the continuous current capability of the device.
The graphs of Power Dissipation vs. Ambient Temperature are showed below :

PCB Layout Consideration
en
The performance of a power source circuit using this device is highly dependent on a peripheral circuit. To
obtain the optimal performance, a peripheral component or the device mounted on PCB should not exceed its
rated voltage, rated current or rated power. When designing a peripheral circuit, guidelines below for PCB
layout of AW37030YXXX should be obeyed:
fid
1. All peripheral components should be placed as close to the chip as possible. CIN and COUT should be close
to IN and OUT pins respectively. Avoid connecting device and chip pins with two different layers of copper,
use the same layer of copper instead.
2. IN and OUT pin are the large current input and output of the chip, make IN, OUT, and meanwhile GND
lines sufficient.
on
3. The connection lines between the planes of CIN or COUT and respective chip pin should be as short and
wide as possible, to reduce noise and EMI interference, or it may cause noise pickup or unstable operation.
aw
ini
cC
4. The exposed plane of chip and GND pins must be connected to the large-area ground layer of PCB directly,
meanwhile place sufficient vias below the exposed plane. Thus we can decrease the thermal resistor on
the board to optimize heat-diffusion performance.
