AME 300mA CMOS LDO with RESET Function AME1300 n General Description n Applications The AME1300 combines a Low Dropout Regulator and a Microprocessor Reset Monitor in a space-saving MSOP8 package. Total supply current is 50µA (typical), 20 to 60 times lower than in bipolar regulators . l Instrumentation The AME1300 has an extremely precise output with a l PC Peripherals typical accuracy of ±1.5%. Other key features include ultra low noise operation, very low dropout voltage and internal feed-forward compensation for fast response to step changes in load. The AME1300 incorporates both over-temperature and over-current protection. When the shutdown control EN is low, the regulator output voltage falls to zero, RESETB output remains valid and supply current is reduced to 10µA(typical). The AME1300 is stable with an output capacitor of only 2.2µF and has a minimum output current of 300 mA. l Portable Electronics l Wireless Devices l Cellular / GSM / CDMA Phones l Battery Powered Widgets n Typical Applications RESETB RESETB VDET VDET V DET and VOUT can be connected together VOUT OUT An active low RESET is asserted when the detected voltage (V DET) falls below the reset voltage threshold. The reset output remains low for 300msec(typical) after VDET rises above reset threshold. The AME1300 also has a fast wake up response time (10µsec typically) when released from shutdown.

Unlike bipolar regulators, the AME1300 supply current does not increase with load current. In addition,VOUT remains stable and within regulation at very low load currents(an important consideration in RTC and CMOS RAM battery backup applications) as well as with any type of capacitor (see below). AME1300 pin functions are detailed below: RESETB RESETB C1 2.2µF VDET IN OUT GND VDET 1300 BYP NC C1 1µF + Battery EN CBypass EN Control (Option) (from Power 470pF Control Logic) n Pin Description Pin Number Pin Name 1 RESETB 2 OUT Regulated Voltage Output. 3 GND Ground Terminal. 4 BYP Reference Bypass Input. Connecting a 1000pF to this input further reduces output noise. Rev.C.02 Pin Description RESETB output remains low while VDET is below the reset voltage threshold, and for 300msec VDET rises above reset theshold. 5 EN Shutdown Control Input. The regulator is fully enabled when a logic high is applied to this input. The regulator enters shutdown when a logic low is applied to this input. During shutdown, regulator output voltage falls to zero, RESETB output remains valid and supply current is reduced to 10µA (typ.) 6 NC No connect. 7 IN Power Supply Input. 8 VDET Detected input Voltage. VDET and VOUT can be connected together. 7 AME AME1300 300mA CMOS LDO with RESET Function n Enable When actively pulled low, the PMOS pass transistor shuts off, and all internal circuits are powered down. In this state, the quiescent current is less than 10µA. This pin behaves much like an electronic switch. RESETB Output The RESETB output is driven active low within 40µsec of VDET falling through the reset threshold.RESETB is maintained active for a minimum of 140msec after VDET rises above the reset threshold. The AME1300 has an active-low RESETB output. The output of the AME1300 is guaranteed vaild down to V DET = 1V and is optimized to reject fast transient glitches on the VDET line. n External Capacitors The AME1300 is stable with an output capacitor to ground of 2.2µF or greater. Ceramic capacitors have the lowest ESR, and will offer the best AC performance. Conversely, Aluminum Electrolytic capacitors exhibit the highest ESR, resulting in the poorest AC response. Unfortunately, large value ceramic capacitors are comparatively expensive. One option is to parallel a 0.1µF ceramic capacitor with a 10µF Aluminum Electrolytic. The benefit is low ESR, high capacitance, and low overall cost. A second capacitor is recommended between the input and ground to stabilize Vin. The input capacitor should be at least 0.1µF to have a beneficial effect. A third capacitor can be connected between the BYPASS pin and GND. This capacitor can be a low cost Polyester Film variety between the value of 0.001~0.01µF. A larger capacitor improves the AC ripple rejection,but also makes the output come slowly. This“ Soft” turn-on is desirable in some applications to limit turn-on surges. All capacitors should be placed in close proximity to the pins. A “ Quiet” ground termination is desirable. This can be achieved with a “ Star” connection. 8 Rev.C.02 AME 300mA CMOS LDO with RESET Function AME1300 Reset VOL vs. Temperature Reset Time vs. Temperature 220 0.265 215 0.255 Reset Time (mS) Reset VOL @ 0.8mA (V) 0.260 0.250 0.245 0.240 0.235 0.230 210 205 200 195 0.225 0.220 -45 -5 25 55 85 190 -45 115 -5 Reset Vth vs. Temperature 55 85 115 Dropout Voltage vs. Temp. 2.650 Dropout Voltage @ 300mA (mV) 230 2.648 2.646 2.644 Reset Vth (V) 25 Temperature (oC) Temperature (oC) 2.642 2.640 2.638 Vth=2.63V 2.636 2.634 2.632 2.630 -45 -5 25 55 85 115 Temperature (oC) 220 210 200 Vout=3.0V 190 180 170 160 150 -45 -5 25 55 85 115 Temperature (oC) Load Regulation vs. Temp.
