AP7335
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.

Application Note
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.

COUT ESR (Ω)
NEW PRODUCT
Input Capacitor
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.

The output voltage is calculated by:
⎛
R ⎞
VOUT = VREF ⎜⎜1 + 1 ⎟⎟
⎝ R2 ⎠
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:
⎛V
⎞
R1 = R2 ⎜⎜ OUT − 1⎟⎟
V
⎝ REF
⎠
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.
Current Limit Protection
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.
Short Circuit Protection
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 from over-current and damage due to overheating.

Application Note (Continued)
NEW PRODUCT
Thermal Shutdown Protection
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.
Ultra Fast Start-up
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.
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.
Low Quiescent Current
The AP7335, consuming only around 35µA for all input range, provides great power saving in portable and low
power applications.
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]) =
