300mA, Low Quiescent Current, Fast Transient
Low Dropout Linear Regulator
Pin Assignments
Description
NEW PRODUCT
The AP7335 is a 300mA, adjustable and fixed output voltage,
low dropout linear regulator. The device included pass
element, error amplifier, band-gap, current limit and thermal
shutdown circuitry. The device is turned on when EN pin is
set to logic high level.
The characteristics of low dropout voltage and low quiescent
current make it suitable for low power applications, for
example, battery powered devices. The typical quiescent
current is approximately 35μA. Built-in current-limit and
thermal-shutdown functions prevent IC from damage in fault
conditions.

3. Dropout voltage is the voltage difference between the input and the output at which the output voltage drops 2% below its nominal
value. This parameter only applies to input voltages above minimum VIN = 2.0V.
4. At VIN < 2.3V, the PSRR performance may be reduced.
5. Test condition for all packages: Device mounted on FR-4 substrate PC board, 1oz copper, with minimum recommended pad
layout.

Application Note
Input Capacitor
The output voltage is calculated by:
⎛
R ⎞
VOUT = VREF ⎜⎜1 + 1 ⎟⎟
R
2⎠
⎝
Where VREF=0.8V (the internal reference voltage)
Rearranging the equation will give the following that is
used for adjusting the output to a particular voltage:
Output Capacitor
The output capacitor is required to stabilize and improve
the transient response of the LDO. The AP7335 is stable
with very small ceramic output capacitors. Using a ceramic
capacitor value that is at least 1μF with ESR > 15mΩ on
the output ensures stability. Higher capacitance values
help to improve line and load transient response. The
output capacitance may be increased to keep low
undershoot and overshoot. Output capacitor must be
placed as close as possible to OUT and GND pins.

R
⎛V
⎞
R1 = R2 ⎜⎜ OUT − 1⎟⎟
⎝ VREF
⎠
To maintain the stability of the internal reference voltage,
R2 need to be kept smaller than 80kΩ.
No Load Stability
Other than external resistor divider, no minimum load is
required to keep the device stable. The device will remain
stable and regulated in no load condition.
ON/OFF Input Operation
The AP7335 is turned on by setting the EN pin high, and is
turned off by pulling it low. If this feature is not used, the
EN pin should be tied to IN pin to keep the regulator
output on at all time. To ensure proper operation, the
signal source used to drive the EN pin must be able to
swing above and below the specified turn-on/off voltage
thresholds listed in the Electrical Characteristics section
under VIL and VIH.
Unstable Range
COUT ESR (Ω)
NEW PRODUCT
A 1μF ceramic capacitor is recommended between IN and
GND pins to decouple input power supply glitch and noise.
The amount of the capacitance may be increased without
limit. This input capacitor must be located as close as
possible to the device to assure input stability and reduce
noise. For PCB layout, a wide copper trace is required for
both IN and GND pins. A lower ESR capacitor type allows
the use of less capacitance, while higher ESR type
requires more capacitance.

When output current at OUT pin is higher than current limit
threshold, the current limit protection will be triggered and
clamp the output current to approximately 600mA to
prevent over-current and to protect the regulator from
damage due to overheating.

Adjustable Operation
The AP7335 provides output voltage from 0.8V to 5.0V
through external resistor divider as shown below.

When OUT pin is short-circuit to GND, short circuit
protection will be triggered and clamp the output current to
approximately 140mA. This feature protects the regulator

Thermal protection disables the output when the junction
temperature rises to approximately +145°C, allowing the
device to cool down. When the junction temperature
reduces to approximately +130°C the output circuitry is
enabled again. Depending on power dissipation,
thermal resistance, and ambient temperature, the
thermal protection circuit may cycle on and off.
This cycling limits the heat dissipation of the regulator,
protecting
it from damage
due
to
overheating.

300mA, Low Quiescent Current, Fast Transient
Low Dropout Linear Regulator
Application Note (Continued)
Ultra Fast Start-up
Low Quiescent Current
After enabled, the AP7335 is able to provide full power in
as little as tens of microseconds, typically 220µs, without
sacrificing low ground current. This feature will help load
circuitry move in and out of standby mode in real time,
eventually extend battery life for mobile phones and other
portable devices.
The AP7335, consuming only around 35µA for all input
range, provides great power saving in portable and low
power applications.
NEW PRODUCT
Fast Transient Response
Fast transient response LDO can extend battery life.
TDMA-based cell phone protocols such as Global System
for Mobile Communications (GSM) have a transmit/receive
duty factor of only 12.5 percent, enabling power savings
by putting much of the baseband circuitry into standby
mode in between transmit cycles. In baseband circuits, the
load often transitions virtually instantaneously from 100µA
to 100mA. To meet this load requirement, the LDO must
react very quickly without a large voltage drop or
overshoot — a requirement that cannot be met with
conventional, general-purpose LDO.
The AP7335’s fast transient response from 0 to 300mA
provides stable voltage supply for fast DSP and GSM
chipset with fast changing load.
Wide Output Range
The AP7335, with a wide output range of 0.8V to 5.0V,
provides a versatile LDO solution for many portable
applications.
Power Dissipation
The device power dissipation and proper sizing of the
thermal plane that is connected to the thermal pad is
critical to avoid thermal shutdown and ensure reliable
operation. Power dissipation of the device depends on
input voltage and load conditions and can be calculated by:
PD = (VIN - VOUT) X IOUT
The maximum power dissipation, handled by the device,
depends on the maximum junction to ambient thermal
resistance, maximum ambient temperature, and maximum
device junction temperature, which can be calculated by
the equation in the following:
PD ([email protected]) =
