19-0663; Rev 0; 10/06 40V, Ultra-Low Quiescent-Current Linear Regulators in 6-Pin TDFN/8-Pin SO The MAX15006/MAX15007 ultra-low quiescent-current linear regulators are ideal for use in automotive and battery-operated systems. These devices operate from an input voltage of 4V to 40V, deliver up to 50mA of output current, and consume only 10µA of quiescent current at no load. The internal p-channel pass device keeps the quiescent current low even at full load. The MAX15007 consumes only 3µA current when in shutdown. The MAX15006A/MAX15007A have a fixed 3.3V output while the MAX15006B/MAX15007B have a fixed 5V output voltage. The MAX15007 includes an enable input to turn the device on or off. All devices are short-circuit protected and include thermal shutdown. The MAX15006/MAX15007 operate over the -40°C to +125°C automotive temperature range. These devices are available in space-saving 3mm x 3mm 6-pin TDFN and 8-pin SO thermally enhanced packages.

These devices guarantee 50mA load drive, and offer preset output voltages of +3.3V or +5V. Thermal shutdown and short-circuit protection prevent damage during overtemperature and overcurrent conditions. The MAX15007 includes an enable input (EN) allowing the regulators to be turned on/off using a logic-level voltage. Driving EN high turns on the device while driving EN low places the device in a low-power shutdown mode. In shutdown, the supply current is reduced to 3µA (typ). The MAX15006/MAX15007 operate over the -40°C to +125°C automotive temperature range. All devices are available in thermally enhanced 6-pin TDFN and 8-pin SO packages capable of dissipating 1.904W and 1.860W at TA = +70°C, respectively. state driver in high-impedance mode, or an open-drain driver. While in shutdown, the device consumes only 3µA (typ). EN withstands voltages up to 40V, allowing it to be driven by high input level voltages or connected to IN for always-on operation. Thermal Protection When the junction temperature exceeds +165°C, an internal thermal sensor turns the pass transistor off, and allows the device to cool. The thermal sensor turns the pass transistor on again after the junction temperature cools by 20°C. This results in a cycled output during continuous thermal-overload conditions. Thermal protection protects the MAX15006/MAX15007 in the event of fault conditions. Operation at TJ = +150°C without going into thermal shutdown is not guaranteed. Use Figures 3a and 3b to determine the minimum guaranteed output current. Output Short-Circuit Current Limit The MAX15006/MAX15007 feature a 175mA current limit. The output can be shorted to GND for an indefinite period of time without damage to the device. During a short circuit, the power dissipated across the pass transistor can quickly heat the device. When the die temperature reaches +165°C, the MAX15006/ MAX15007 shut down and automatically restart after the die temperature cools by 20°C.

Output-Capacitor Selection and Regulator Stability For stable operation over the full temperature range and with load currents up to 50mA, use a low-ESR 2.2µF (min) ceramic or tantalum output capacitor. Use larger output-capacitor values such as 22µF to reduce noise, improve load-transient response, and powersupply rejection. Some ceramic dielectrics exhibit large capacitance and ESR variations with temperature. Ensure the minimum capacitance under worst-case conditions does not drop below 1.3µF to ensure output stability. With an X7R dielectric, 2.2µF should be sufficient at all operating temperatures. In Examples 2 and 3, the maximum output current is calculated as 172mA and 476mA, respectively; however, the allowable output current cannot exceed 50mA.
