MAX8877/MAX8878 __________________General Description The MAX8877/MAX8878 low-noise, low-dropout linear regulators operate from a 2.5V to 6.5V input and deliver up to 150mA. These devices are pin-compatible with the industry-standard '2982 and offer an improved dropout voltage. Typical output noise is 30µVRMS, and typical dropout is only 165mV at 150mA. The output voltage is preset to voltages in the range of 1.5V to 5.0V, in 100mV increments. Designed with an internal P-channel MOSFET pass transistor, the MAX8877/MAX8878 maintain a low 100µA supply current, independent of the load current and dropout voltage. Other features include a 10nA logic-controlled shutdown mode, short-circuit and thermal-shutdown protection, and reverse battery protection. The MAX8878 also includes an auto-discharge function, which actively discharges the output voltage to ground when the device is placed in shutdown. Both devices come in regular and thin 5-pin SOT23 packages.

The parts are available with preset output voltages ranging from 1.5V to 5V, in 100mV increments. These devices can supply loads up to 150mA. As illustrated in Figure 1, the MAX8877/MAX8878 consist of a 1.25V reference, error amplifier, P-channel pass transistor, and internal feedback voltage divider. The 1.25V 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 IN SHDN 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 voltage divider connected to the OUT pin. An external bypass capacitor connected to the BP pin reduces noise at the output. Additional blocks include a current limiter, reverse battery protection, thermal sensor, and shutdown logic. The MAX8878 also includes an auto-discharge function, which actively discharges the output voltage to ground when the device is placed in shutdown mode.

Functional Diagram 6 _______________________________________________________________________________________ Low-Noise, Low-Dropout, 150mA Linear Regulators with '2982 Pinout Internal P-Channel Pass Transistor The MAX8877/MAX8878 feature a 1.1Ω typical P-channel MOSFET pass transistor. This provides several advantages over similar designs using PNP pass transistors, including longer battery life. The P-channel MOSFET requires no base drive, which reduces quiescent current considerably. PNP-based regulators waste considerable current in dropout when the pass transistor saturates. They also use high base-drive currents under large loads. The MAX8877/MAX8878 do not suffer from these problems and consume only 100µA of quiescent current whether in dropout, light-load, or heavy-load applications (see the Typical Operating Characteristics). Current Limit The MAX8877/MAX8878 include a current limiter, which monitors and controls the pass transistor’s gate voltage, limiting the output current to 390mA. For design purposes, consider the current limit to be 160mA minimum to 500mA maximum. The output can be shorted to ground for an indefinite amount of time without damaging the part. Thermal-Overload Protection Thermal-overload protection limits total power dissipation in the MAX8877/MAX8878. When the junction temperature exceeds T J = +155°C, the thermal sensor signals the shutdown logic, turning off the pass transistor and allowing the IC to cool. The thermal sensor will turn the pass transistor on again after the IC’s junction temperature cools by 15°C, resulting in a pulsed output during continuous thermal-overload conditions. Thermal-overload protection is designed to protect the MAX8877/MAX8878 in the event of fault conditions. For continual operation, do not exceed the absolute maximum junction-temperature rating of TJ = +150°C. Operating Region and Power Dissipation The MAX8877/MAX8878’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. The power dissipation across the device is P = IOUT (VIN - VOUT). The maximum power dissipation is: PMAX = (TJ - TA) / (θJB + θBA) where TJ - TA is the temperature difference between the MAX8877/MAX8878 die junction and the surrounding air, θJB (or θJC) is the thermal resistance of the package, and θBA is the thermal resistance through the printed circuit board, copper traces, and other materials to the surrounding air. The GND pin of the MAX8877/MAX8878 performs the dual function of providing an electrical connection to ground and channeling heat away. Connect the GND pin to ground using a large pad or ground plane. Reverse Battery Protection The MAX8877/MAX8878 have a unique protection scheme that limits the reverse supply current to 1mA when either VIN or V SHDN falls below ground. Their circuitry monitors the polarity of these two pins and disconnects the internal circuitry and parasitic diodes when the battery is reversed. This feature prevents device damage. Noise Reduction An external 0.01µF bypass capacitor at BP, in conjunction with an internal 200kΩ resistor, creates a 80Hz lowpass filter for noise reduction. The MAX8877/MAX8878 exhibit 30µVRMS of output voltage noise with CBP = 0.01µF and COUT = 10µF. This is negligible in most applications. Start-up time is minimized by a power-on circuit that pre-charges the bypass capacitor. The Typical Operating Characteristics section shows graphs of Noise vs. BP Capacitance, Noise vs. Load Current, and Output Noise Spectral Density. ____________Applications Information Capacitor Selection and Regulator Stability Normally, use a 1µF capacitor on the MAX8877/ MAX8878’s input and a 1µF to 10µF capacitor on the output. Larger input capacitor values and lower ESRs provide better supply-noise rejection and line-transient response. Reduce noise and improve load-transient response, stability, and power-supply rejection by using large output capacitors. For stable operation over the full temperature range and with load currents up to 150mA, a 1µF (min) ceramic capacitor is recommended for VOUT ≥ 2.5V and 3.3µF and for VOUT < 2.5V. 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, 1µF should be sufficient at all operating temperatures for VOUT ≥ 2.5V. A graph of the Region of _______________________________________________________________________________________ 7 MAX8877/MAX8878 Output Voltage The MAX8877/MAX8878 are supplied with factory-set output voltages from 1.5V to 5.0V, in 100mV increments. Except for the MAX887_EUK29 and the MAX887_EUK32 (which have an output voltage preset at 2.84V and 3.15V, respectively), the two-digit suffix allows the customer to choose the output voltage in 100mV increments. For example, the MAX8877EUK33 has a preset output voltage of 3.3V (see Expanded Ordering Information). MAX8877/MAX8878 Low-Noise, Low-Dropout, 150mA Linear Regulators with '2982 Pinout Stable C OUT ESR vs. Load Current is shown in the Typical Operating Characteristics. Use a 0.01µF 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 0.1µF provide no performance advantage and are not recommended (see Shutdown Exit Delay graphs in the Typical Operating Characteristics). PSRR and Operation from Sources Other than Batteries The MAX8877/MAX8878 are designed to deliver low dropout voltages and low quiescent currents in batterypowered systems. Power-supply rejection is 63dB at low frequencies and rolls off above 10kHz. See the Power-Supply Rejection Ratio Frequency graph in the Typical Operating Characteristics. 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. The Typical Operating Characteristics show the MAX8877/MAX8878’s line- and loadtransient responses. Load-Transient Considerations The MAX8877/MAX8878 load-transient response graphs (see Typical Operating Characteristics) 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 0mA to 50mA is 12mV. Increasing the output capacitor’s value and decreasing the ESR attenuates the overshoot. Input-Output (Dropout) Voltage For output voltage greater than the minimum input voltage (2.5V), 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 MAX8877/MAX8878 use a Pchannel MOSFET pass transistor, their dropout voltage is a function of drain-to-source on-resistance (RDS(ON)) multiplied by the load current (see Typical Operating Characteristics). ___________________Chip Information TRANSISTOR COUNT: 247 SUBSTRATE CONNECTED TO GND Expanded Ordering Information OUTPUT VOLTAGE (xy) CODE SOT TOP MARK REGULAR SOT23 THIN SOT23 PRESET OUTPUT VOLTAGE (V) MAX887_EUK15-T MAX887_EZK15-T 1.50 ADRG AAAA ADQV AAAJ MAX887_EUK18-T MAX887_EZK18-T 1.80 ADQT AAAB ADRH AAAK MAX887_EUK25-T MAX887_EZK25-T 2.50 ACBM AAAC ACBT AAAL MAX887_EUK28-T MAX887_EZK28-T 2.80 ACBN AAAD ACBU AAAM MAX887_EUK29-T MAX887_EZK29-T 2.84 ACBO ADPM ACBV ADPO MAX887_EUK30-T MAX887_EZK30-T 3.00 ACBP AAAE ACBW AAAN MAX887_EUK32-T MAX887_EZK32-T 3.15 ACBQ AAAF ACBX AAAO MAX887_EUK33-T MAX887_EZK33-T 3.30 ACBR AAAG ACBY AAAP MAX887_EUK36-T MAX887_EZK36-T 3.60 ACDB AAAH ACDC AAAQ MAX887_EUK50-T MAX887_EZK50-T 5.00 ACBS AAAI ACBZ AAAR x.y0 — — — — Other xy*** MAX8877 REGULAR MAX8877 THIN MAX8878 REGULAR MAX8878 THIN ***Other xy between 1.5V and 5.0V are available in 100mV increments.
