FP6121
300mA, High PSRR, Dual Output
Low-Dropout Regulator
Description
Features
The FP6121 is a dual output, low dropout, high
PSRR, low quiescent current linear regulators. The
FP6121 can supply 200mA output current with a
lower dropout voltage about 300mV for each
channel.
Low Dropout Voltage: 300mV at IOUT=200mA
Guaranteed 300mA Output Current Per Channel
Very Low Quiescent Current: 25μA
High Power Supply Rejection Ratio: 70dB at
10kHz
Highly Accurate: 2%
The FP6121 is suitable for portable and wireless
application such as mobile phone and portable
hand-sets. The FP6121 is designed and optimized
to work with low-value, low cost ceramic capacitors.
The FP6121 consumes less than 0.1μA during
shutdown mode which is independent for each

channel,
allowing for flexibility in power
management. Besides its current limit protection
and on chip thermal shutdown features provide
protection against any combination of overload or
ambient temperature that could exceed junction
temperature.
Applications
Mobile Phone
Portable or Wireless Instrument
Camera
PDA and Notebook Computer
The FP6121 doesn’t need external bypass capacitor
and still could get better noise performance. The
tiny SOT-23-6, TSOT-23-6 and TDFN-6 packages
are attractive for hand-held applications.

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.

Application Information
Thermal Consideration
The FP6121 include 2 independent output channels.
Current limit and on chip thermal shutdown features
provide protection against any combination of
overload or ambient temperature that could exceed
maximum junction temperature.
The power handling capability of the device will be
limited by maximum 125C operation junction
temperature. The power dissipated by the device
will be estimated by
EN Control
PD = IOUT (VIN-VOUT
)
Force EN pin high to enable the FP6121 and turned
off the device by pulling it low. The Eꢄ pin can’t be
floated and must be tied to the Vin if not used. The
enable control is independent to each channel.
The power dissipation should be lower than the
maximum power dissipation listed in “Absolute
Maximum Ratings” section.
Capacitor Selection
PSRR (Power Supply Rejection Ratio)
The ceramic capacitor is ideal for FP6121
application. The ESR of the output capacitor
The FP6121 has high 70dB PSRR. Ripple rejection
is the ability of the regulator to reduce input voltage
ripple. It is specified with a 10kHz and 1VP-P signal
affects stability.
Larger value of the output
capacitor decreases the peak deviations and
improves transient response for larger current
changes.
applying to input, with 1μF output capacitor. Ripple
rejection, expressed in dB, is the ratio of output ripple
to input ripple.
The capacitor types (ceramic, aluminum, and
tantalum) have different characterizations such as
voltage and temperature 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 because X5R or X7R hold their
capacitance over wide voltage and temperature
ranges than other Y5V or Z5U types. The ESR of
output capacitor is very important because it
generates a zero to provide phase lead for loop
stability. The input capacitor can reduced peak
current and noise at power source.
Thermal Shutdown
Thermal shutdown is employed to protect the device
damage from the junction temperature exceed safe
margins due mainly to short circuit or current limit.
Moreover, the device returns normally operation
when the junction temperature down to a constant
temperature. Though temperature protection circuit
is built in to protect IC, the maximum power
dissipation design within Tj(max) is needed. The
thermal protection is independent to each channel.
