MAX15006/MAX15007 40V, Ultra-Low Quiescent-Current Linear Regulators in 6-Pin TDFN/8-Pin SO General Description 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 MAX15006C/MAX15007C feature an adjustable output from 1.8V to 10V. 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.

The MAX15006A/MAX15007A have a fixed 3.3V output voltage while the MAX15006B/MAX15007B offer a fixed 5V output voltage. The MAX15006C/MAX15007C feature an adjustable voltage output by connecting an external resistive divider from OUT to FB and to GND (see the Output Voltage Setting section). 30 25 VIN = 26V, VOUT = 5V 20 15 10 VIN = 26V, VOUT = 3.3V 5 0 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. 55 VIN = 18V, VOUT = 5V 50 45 VIN = 18V, VOUT = 3.3V 40 35 MAX15006 fig03b Regulator EN is an active-high, logic-level enable input that turns the device on or off. Drive EN high to turn the device on. An internal 0.5μA pulldown current keeps the MAX15007 in shutdown mode when driven by a three-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. OUTPUT CURRENT (mA) The MAX15006/MAX15007 high-voltage linear regulators operate over a 4V to 40V input voltage range. These devices guarantee 50mA load drive, and offer preset output voltages of +3.3V (MAX15006A/MAX15007A) or +5V (MAX15006B/MAX15007B) or an adjustable voltage output from 1.8V to 10V (MAX15006C/MAX15007C). 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 logiclevel 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 1.509W at TA = +70°C, respectively. 30 25 20 VIN = 26V, VOUT = 5V 15 10 VIN = 26V, VOUT = 3.3V 5 80 85 90 95 100 105 110 115 120 125 130 AMBIENT TEMPERATURE (°C) Figure 3a.

Connect an external resistive divider from OUT to FB to GND as shown in Figure 4 to set the desired output voltage. VOUT is calculated as follows:  R1  VOUT= VFB × 1 +   R2  where VFB = 1.23V and a 5μA minimum current is required in the external divider for stability. Available Output Current Calculation The MAX15006/MAX15007 provide up to 50mA of continuous output current. The input voltage range extends to 40V. Package power dissipation limits the amount of output current available for a given input/output voltage and ambient temperature. Figure 5 shows the maximum allowable power dissipation for these devices to keep the junction temperature below +150°C. Figure 5 assumes that the exposed metal pad of the MAX15006/MAX15007 is soldered to 1in2 of PCB copper. Use Figure 5 to determine the allowable package dissipation for a given ambient temperature. Alternately, use the following formulas to calculate the allowable package dissipation.

Use larger outputcapacitor values such as 22μF to reduce noise, improve load-transient response, and power-supply 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. 60 55 50 45 MAX15006 fig05a TA = +70°C 40 35 30 25 20 15 10 5 0 Alternately, use Figures 6a and 6b to quickly determine the maximum allowable output current for selected ambient temperatures and input voltages.
