SA8877-XX
GENERAL DESCRIPTION
The SA8877-XX family are very low-noise, low-dropout, low
quiescent-current linear regulators designed for battery-powered
applications, although they can also be used for devices powered by
AC-DC converters. The parts are available in a range of preset
output voltages from 2.5 V to 4.5 V. Typical dropout voltages are
only 165 mV at 150 mA, and 55 mV at 50 mA. Reverse battery
current is extremely low, 0.5 µA typ.
For demanding applications, output noise voltage of typically
20 µV
is achieved with a 0.01 µF capacitor on the noise bypass
rms
pin. The input voltage can vary from 2.5 V to 5.5 V , providing
DC
DC
up to150 mA output current.
An internal P-channel FET pass transistor maintains an 85 µA
typical supply current, independent of the load current and dropout
voltage. Other features include a 0.01 µA logic-controlled shutdown,
short circuit and thermal shutdown protection, and reverse battery
protection.
To accommodate high density layouts, it is packaged in the small
footprint 5-pin SO5 (SOT23-5). The SA8877 is pin compatible with
the industry standard ’2982 and a direct replacement for the
MAX8877.

TECHNICAL DISCUSSION
The SA8877-XX family are very low-noise, low-dropout, low
quiescent-current linear regulators designed for battery-powered
applications, although they can also be used for devices powered by
AC-DC converters.
The GND pin provides an electrical connection to ground and a path
for heat transfer away from the junction. Connect the GND pin to
ground using a large pad or ground plane to maximize heat transfer.
Noise reduction
An optional external 0.01 µF bypass capacitor at BP, in conjunction
with an internal 200 Ω resistor, creates an 80 Hz low-pass filter for
The voltage regulation components of the SA8877-XX consist of a
1.23 V reference, an error amplifier, a P-channel pass transistor, and
an internal feed-back voltage divider. The device also contains a
reverse battery protection circuit, a thermal sensor, a current limiter,
and shutdown logic.

of output voltage

most applications.
Voltage regulation
Start-up time is minimized by a power-on circuit that pre-charges the
bypass capacitor. The ‘Typical Performance Curves’ section shows
graphs of ‘Output noise versus BP capacitance’ (Figure 16), ‘Output
noise versus output current’ (Figure 17), and ‘Output noise spectral
density versus frequency’ (Figure 13).
The 1.23 V bandgap reference is connected to the error amplifier’s
inverting input. The error amplifier compares this reference with the
feedback voltage and amplifies the difference. If the feedback
voltage is lower than the reference voltage, the pass-transistor gate
is pulled lower, which allows more current to pass to the output and
increases the output voltage. If the feedback voltage is too high, the
pass-transistor gate is pulled up, allowing less current to pass to the
output. The output voltage is fed back through an internal resistor
Device protection
The SA8877 has several built-in protection circuits.
Current limiter: The current limiter controls the the pass transistor’s
gate voltage so the output current cannot exceed 390 mA. We
recommend using 160 mA minimum to 500 mA maximum in the
design parameters. Because of the current limiter, the output can be
shorted to ground for an indefinite amount of time with no damage to
the part.
voltage divider connected to the V
pin.
OUT
The SA8877 uses a 1.1 Ω typical P-channel MOSFET pass
transistor. The P-channel MOSFET requires no base drive, therefore
the device has lower quiescent current than a comparable PNP
transistor-based design. The SA8877-XX uses 100 µA of quiescent
current under any load conditions.
Reverse battery protection: The reverse battery protection circuit
prevents damage to the device if the supply battery is accidentally

and disconnects the device’s internal circuits if it detects reversed
polarity. Reverse supply current is limited to 1 mA when this
protective circuit is active, preventing the battery from rapidly
discharging through the device.
Power dissipation
The SA8877’s maximum power dissipation depends on the thermal
resistance of the case and circuit board, the temperature difference
between the die junction and ambient air, and the rate of air flow.
Thermal overload protection: When the junction temperature
exceeds +140 °C, the thermal sensor signals the shutdown logic to
turn off the pass transistor. After the junction temperature has cooled
by 15 °C the sensor signals the shutdown logic to turn the pass
transistor on again. This will create a pulsed output during lengthy
thermal overloads.
The power dissipation across the device is P = I
The maximum power dissipation is:

APPLICATION INFORMATION
Capacitor selection and regulator stability
Normally, use a 1 µF capacitor on the SA8877 input and a 1 µF to
10 µF capacitor on the output. To improve the supply-noise rejection
and line-transient response, use input capacitor values and lower
ESRs. To reduce noise and improve load-transient response,
stability, and power-supply rejection, use use large output
capacitors.
PSRR and operation from sources other than
batteries
The SA8877 is designed to deliver low dropout voltages and low
quiescent currents in battery-powered systems. When operating
from sources other than batteries, improved supply-noise rejection
and transient response can be achieved by increasing the values of
the input and output bypass capacitors, and through passive filtering
techniques.
For stable operation over the full temperature range and with load
currents up to 150 mA, a 1 µF (min.) ceramic capacitor is
recommended.
Power-supply rejection is 63 dB at low frequencies and rolls off
above 10 kHz. See Figure 15, ‘Power supply rejection ratio versus
frequency’. Figures 18, 19, and 20 show the SA8877’s line- and
load-transient responses.
Note that some ceramic dielectrics exhibit large capacitance and
ESR variation with temperature. With dielectrics such as Z5U and
Y5V, it may be necessary to increase the capacitance by a factor
of 2 or more to ensure stability at temperatures below –10 °C. With
X7R or X5R dielectrics, 1 µF should be sufficient at all operating
Input-output (dropout) voltage
For output voltage greater than the minimum input voltage (2.5 V),
the regulator’s minimum input-output voltage differential (or dropout
voltage) determines the lowest usable supply voltage. In
battery-powered systems, this will determine the useful end-of-life
battery voltage. Because the SA8877 uses a P-channel MOSFET
pass transistor, the dropout voltage is a function of drain-to-source
temperatures for V
= 2.5 V.

shown in Figure 14. Use a 0.01 µF bypass capacitor at BP for low
output voltage noise. Increasing the capacitance will slightly
decrease the output noise, but increase the start-up time. Values
above 0.1 µF provide no performance advantage and are not
recommended (see Figures 21 and 22 in the ‘Typical Performance
Curves’).
on-resistance (R ) multiplied by the load current (see ‘Typical
DS(ON)
Performance Curves’).
Load-transient considerations
The SA8877 load-transient response graphs (Figures 18, 19, and
20) show two components of the output response: a DC shift from
the output impedance due to the load current change, and the
transient response. Typical transient for a step change in the load
current from 0 mA to 50 mA is 40 mV. Increasing the output
capacitor’s value and decreasing the ESR attenuates the overshoot.
