These regulators achieve a low 120mV dropout for 120mA load current. The MAX8840 uses an advanced architecture to achieve ultra-low output voltage noise of 11µVRMS and PSRR of 54dB at 100kHz. The MAX8841 does not require a bypass capacitor, hence achieving the smallest PC board area. The MAX8842 output voltage can be adjusted with an external divider. The MAX8840/MAX8841 are preset to a variety of voltages in the 1.5V to 4.5V range. Designed with a p-channel MOSFET series pass transistor, the MAX8840/MAX8841/ MAX8842 maintain very low ground current (40µA). The regulators are designed and optimized to work with low-value, low-cost ceramic capacitors. The MAX8840 requires only 1µF (typ) of output capacitance for stability with any load. When disabled, current consumption drops to below 1µA. The MAX8840/MAX8841/MAX8842 are available in a tiny 1mm x 1.5mm x 0.8mm µDFN.

Unregulated Input Supply Detailed Description The MAX8840/MAX8841/MAX8842 are ultra-low-noise, low-dropout, low-quiescent current linear regulators designed for space-restricted applications. The parts are available with preset output voltages ranging from 1.5V to 4.5V. These devices can supply loads up to 150mA. As shown in the Functional Diagram, the MAX8840/MAX8841 consist of an innovative bandgap core and noise bypass circuit, error amplifier, p-channel pass transistor, and internal feedback voltagedivider. The MAX8842 allows for adjustable output with an external feedback network. The 1.225V 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 low. This 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 high, 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. reduces quiescent current. PNP-based regulators waste considerable current in dropout when the pass transistor saturates. They also use high base-drive current under heavy loads. The MAX8840/MAX8841/MAX8842 do not suffer from these problems and consume only 40µA of quiescent current in light load and 220µA in dropout (see the Typical Operating Characteristics). Output Voltage Selection The MAX8840/MAX8841 are supplied with factory-set output voltages from 1.5V to 4.5V, in 100mV increments (see the Ordering Information). The MAX8842 features a user-adjustable output through an external feedback network (see the Typical Operating Circuits). To set the output of the MAX8842, use the following equation: ⎛ VOUT ⎞ R1 = R2 X ⎜ - 1⎟ ⎝ VREF ⎠ where R2 is chosen to be less than 240kΩ and VREF = 1.225V. Use 1% or better resistors. Shutdown Internal p-Channel Pass Transistor The MAX8840/MAX8841/MAX8842 feature a low-power shutdown mode that reduces quiescent current less than 1µA. Driving SHDN low disables the voltage reference, error amplifier, gate-drive circuitry, and pass transistor (see the Functional Diagram), and the device output enters a high-impedance state. Connect SHDN to IN for normal operation. The MAX8840/MAX8841/MAX8842 feature a 1Ω (typ) p-channel MOSFET pass transistor. This provides several advantages over similar designs using a pnp pass transistor, including longer battery life. The p-channel MOSFET requires no base drive, which considerably The MAX8840/MAX8841/MAX8842 include a current limiter, which monitors and controls the pass transistor’s gate voltage, limiting the output current to 200mA. An external bypass capacitor connected to BP (MAX8840) reduces noise at the output. Additional blocks include a current limiter, thermal sensor, and shutdown logic. 6 Current Limit _______________________________________________________________________________________ Ultra-Low-Noise, High PSRR, Low-Dropout, 150mA Linear Regulators in µDFN Thermal-Overload Protection Thermal-overload protection limits total power dissipation in the MAX8840/MAX8841/MAX8842. When the junction temperature exceeds TJ = +160°C, the thermal sensor signals the shutdown logic, turning off the pass transistor and allowing the IC to cool down. The thermal sensor turns the pass transistor on again after the IC’s junction temperature drops by 10°C, resulting in a pulsed output during continuous thermal-overload conditions. Thermal-overload protection is designed to protect the MAX8840/MAX8841/MAX8842 in the event of a fault condition. For continual operation, do not exceed the absolute maximum junction temperature rating of TJ = +150°C. Operating Region and Power Dissipation The MAX8840/MAX8841/MAX8842 maximum power dissipation depends on the thermal resistance of the case and circuit board, the temperature difference between the die junction and ambient, and the rate of airflow. The power dissipation across the device is: P = IOUT (VIN - VOUT) The maximum power dissipation is: PMAX = (TJ - TA) / (θJC + θCA) where TJ - TA is the temperature difference between the MAX8840/MAX8841/MAX8842 die junction and the surrounding air, θJC is the thermal resistance of the package, and θCA is the thermal resistance through the PC board, copper traces, and other materials to the surrounding air. The GND pin of the MAX8840/MAX8841/MAX8842 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. Applications Information Capacitor Selection and Regulator Stability Use a 1µF capacitor on the MAX8840/MAX8841/ MAX8842 input and a 1µF capacitor on the output. Larger input capacitor values and lower ESRs provide better noise rejection and line-transient response. Reduce output noise and improve load-transient response, stability, and power-supply rejection by using large output capacitors. 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 use a 2.2µF or larger output capacitor to ensure stability at temperatures below -10°C. With X7R or X5R dielectrics, 1µF is sufficient at all operating temperatures. A graph of the Region of Stable COUT ESR vs. Load Current is shown in the Typical Operating Characteristics. Use a 0.01µF bypass capacitor at BP (MAX8840) for low-output voltage noise. The leakage current going into the BP pin should be less than 10nA. Increasing the capacitance slightly decreases the output noise. Values above 0.1µF and below 0.001µF are not recommended. Noise, PSRR, and Transient Response The MAX8840/MAX8841/MAX8842 are designed to deliver ultra-low noise and high PSRR, as well as low dropout and low quiescent currents in battery-powered systems. The MAX8840 power-supply rejection is 78dB at 1kHz and 54dB at 100kHz. The MAX8841/MAX8842 PSRR is 72dB at 1kHz and 46dB at 100kHz (see the Power-Supply Rejection Ratio vs. 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 MAX8840/MAX8841/MAX8842 line- and loadtransient responses. Noise Reduction Dropout Voltage For the MAX8840, an external 0.01µF bypass capacitor between BP and OUT with an innovative noise bypass scheme reduces output noises dramatically, exhibiting 11µVRMS of output voltage noise with CBP = 0.01µF and COUT = 1µF. Startup time is minimized by a poweron circuit that precharges the bypass capacitor. A regulator’s minimum dropout voltage determines the lowest usable supply voltage. In battery-powered systems, this determines the useful end-of-life battery voltage. Because the MAX8840/MAX8841/MAX8842 use a p-channel MOSFET pass transistor, their dropout voltage is a function of drain-to-source on-resistance (RDS(ON)) multiplied by the load current (see the Typical Operating Characteristics). _______________________________________________________________________________________ 7 MAX8840/MAX8841/MAX8842 For design purposes, consider the current limit to be 150mA (min) to 300mA (max). The output can be shorted to ground for an indefinite amount of time without damaging the part.
