Low Input Voltage, Low-Dropout
200mA Linear Regulator
Description
Features
The FP6161 is a CMOS low dropout, positive linear
regulator with input voltage down to about 1.65V.
The FP6161 can deliver a guaranteed 200mA load
current with a low dropout voltage.
● Very Low Input Voltage at 1.65V (min.)
● Guaranteed 200mA Output Current
● Very Low Quiescent Current at 40μA
● Shutdown Function
● Output Voltage Accuracy at 2.5%
● Thermal Shutdown and Current Limit Protection
Functions
● Low-ESR Ceramic Capacitor for Output Stability
● RoHS Compliant
The FP6161 is suitable for portable application such
as cellular handsets or PDA. The FP6161 is
designed and optimized to work with low cost
ceramic capacitors. The FP6161 consumes less
than 0.1µA during shutdown mode. Besides, its
current limit protection and on-chip thermal
shutdown function provide protection against any
combination of over-load or ambient temperature
which could cause junction temperature exceeding
maximum rating.
● Tiny SOT-23-5, TSOT-23-5 and TDFN-6 Packages
Applications
● PDA and Notebook Computer
● Battery Power System
● GSM and CDMA Cellular Handset
● Wireless Device
The FP6161 includes a reference bypass pin in
order to reduce output noise and a logic control
shut-down input.
● DSC and MP3 Player
The space-saving tiny 5-pin SOT-23-5, TSOT-23-5
and 6-pin TDFN packages are attractive for
hand-held applications.

Functional Pin Description
Pin Name
Pin Function
Power is supplied to this device from this pin which requires an input filter capacitor. In general, the input
capacitor in the range of 1µF to 10µF is sufficient.
VIN
The output supplies power to loads. The output capacitor is required to prevent output voltage unstable. The
FP6161 is stable with an output capacitor which is 1µF or greater. The larger output capacitor will be required
for application with large transient load to limit peak voltage transits. Besides, it could reduce output noise,
improve stability and PSRR.
VOUT
GND
BP
Common ground pin.
The noise bypass pin. The BP pin is used to augment the internal low pass filter to improve noise performance.
Any value of capacitor may be used. Larger value will result in lower output noise. If it is not used, this pin
must be left unconnected.
Logic input controls the device active or shut off. The shutdown pin can’t be left floating and must be tied to the
VIN pin if it’s not used.

Application Information
The FP6161 series are low dropout linear regulators
that could provide 200mA output current at low input
voltage. Besides, current limit and on chip thermal
shutdown features provide protection against any
combination of over-load or ambient temperature
which could cause junction temperature exceeding
maximum rating.
Protection Features
In order to prevent overloading or thermal
condition from damaging the device, FP6161
regulator has internal thermal and current limit
functions designed to protect the device. It will
rapidly shut off PMOS pass element during
over-loading or over-temperature condition.
Output and Input Capacitor
Thermal Consideration
The FP6161 regulator is designed to be stable with a
wide range of output capacitors. The ESR of the
output capacitor affects stability. Larger value of the
output capacitor decreases the peak deviations and
improves transition response for larger current
changes.
The power handling capability of the device will be
limited
temperature (125C). The power dissipated by
the device will be estimated by PD = IOUT
by
allowable
operation
junction
(VIN-VOUT). The power dissipation should be
lower than the maximum power dissipation listed
in “Absolute Maximum Ratings” section.
The capacitor types (aluminum, ceramic and
tantalum) have different characterizations such as
temperature and voltage coefficients. All ceramic
capacitors are manufactured with a variety of
dielectrics, each with different behavior across
temperature and applications. Common dielectrics
used are X5R, X7R and Y5V. It is recommended to
use 1µF to 10µF X5R or X7R dielectric ceramic
capacitors with 30mΩ to 50mΩ EꢀR range between
device outputs to ground for transient stability. The
FP6161 is designed to be stable with low ESR
ceramic capacitors and higher values of capacitors,
and ESR could improve output stability. So the
ESR of output capacitor is very important because it
generates a zero to provide phase lead for loop
stability.
Noise Bypass Capacitor
The BP pin connecting a 0.01µF or 0.001µF
capacitor could reduce noise and lightly improve
PSRR on the regulator output. CBP is optional for
minimizing output noise.
Active/Shutdown Input Operation
The FP6161 is turned off by pulling the ꢀꢁꢂꢃ pin
low and turned on by pulling it high. If this
feature is not used, the ꢀꢁꢂꢃ pin should be
connected to VIN to keep the regulator output
available all the time.
There are no requirements for the ESR on the input
capacitor, but its voltage and temperature coefficient
have to be considered for device application
environment.
