DATA SHEET AAT2605 Five-Channel 300mA LDO Regulator General Description Features The AAT2605 is a member of Skyworks' Total Power Management IC (TPMIC™) product family. It contains five fully integrated 300mA low dropout (LDO) regulators in a small Pb-free 14-pin 3mm x 3mm TDFN package, making it ideal for space-constrained systems. • 2.7V to 5.5V Operating Input Voltage Range • 5 Outputs with Factory Programmable Voltages from 0.6V to 3.7V • 300mA Output Current Per Channel • 3mmx3mm, 14-Pin TDFN Package • ±1% Typical Accuracy • Low 30µA Quiescent Current • High PSRR (68dB @10KHZ) • 250mV Dropout Voltage at 250mA • Independent Enable • Over-Current Protection • Over-Thermal Protection The AAT2605 features low power consumption, low dropout, and high noise immunity from the input power supply. Each channel consumes a mere 30µA of current when enabled, features 250mV of dropout at 250mA and 68dB of power supply rejection at 10kHz. Each channel has its own enable pin and uses a small 1µF output capacitor. Output voltages are factory One Time Programmable (OTP) between 0.6V and 3.7V with 100mV increment and typical regulation accuracy is ±1%. LDO1 and LDO2 share the same input voltage, as do LDO3 and LDO4 while LDO5 has its own independent input. Applications • Cellular Applications • Handheld Products • Media Players (MP4 Players) • Portable Navigation Devices (PND) The AAT2605 is a safe solution that integrates an overcurrent limit for each channel and an over-thermal protection. The device is rated over a temperature range of -40°C to 85°C.

The regulators operate from the 2.7V to 5.5V input voltage to a regulated output voltage. Each LDO regulator has its own independent enable pin. The LDO regulators have a fixed output programmed during manufacturing. Each LDO consumes 30μA of quiescent current and is stable with a small 1.0μF ceramic output capacitor. These LDOs offer high power supply rejection, over-current protection and over-temperature protection. 8 OTP Application Information Input Capacitor Typically, a 2.2μF or larger ceramic capacitor is recommended for CVCC, CVIN3/4, and CVIN5 in most applications. The input capacitor should be located as close to the input (VIN) of the device as practically possible. CVIN values greater than 2.2μF will offer superior input line transient response and will assist in maximizing the highest possible power supply ripple rejection.

The COUT capacitor connection to the LDO regulator ground pin should be made as direct as practically possible for maximum device performance. The AAT2605's LDO regulators have been specifically designed to function with very low ESR ceramic capacitors. Although the device is intended to operate with these low ESR capacitors, it is stable over a very wide range of capacitor ESR, thus it will also work with higher ESR tantalum or aluminum electrolytic capacitors. However, for best performance, ceramic capacitors are recommended. PLDO2 = ILDO2 · (VCC - VO2) PLDO3 = ILDO3 · (VIN3/4 - VO3) PLDO4 = ILDO4 · (VIN3/4 - VO4) PLDO5 = ILDO5 · (VIN5 - VO5) PTOTAL = PLDO1 + PLDO2 + PLDO3 + PLDO4 + PLDO5 Layout Typical output capacitor values for maximum output current conditions range from 1μF to 10μF. The suggested PCB layout for the AAT2605 is shown in Figures 2 and 3. The following guidelines should be used to help ensure a proper layout. Thermal Calculations 1. The input capacitors (C1, C2 and C3 should connect as closely as possible to VCC, VIN3/4 and VIN5 (Pins 5, 6 and 8) and GND (Pin 7). 2. The resistance of the trace from the load return to GND (Pin 7) should be kept to a minimum. This will help to minimize any error in DC regulation due to differences in the potential of the internal signal ground and the power ground. 3. For good thermal coupling, PCB vias are required from the pad for the TDFN33-14's exposed paddle to the ground plane. There are two types of losses associated with the AAT2605 total power management solution (five LDO regulators): conduction losses and quiescent current losses. Conduction losses are associated with the power loss of the voltage difference across the pass switch/FET of the five LDO regulators. At full load, a simplified form of the losses is given by the following (quiescent losses are ignored, since conduction losses are so dominant): Skyworks Solutions, Inc. • Phone [781] 376-3000 • Fax [781] 376-3100 • [email protected] • www.skyworksinc.com 202183A • Skyworks Proprietary Information • Products and Product Information are Subject to Change Without Notice. • July 24, 2012 9 DATA SHEET AAT2605 Five-Channel 300mA LDO Regulator VCC TP1 C1 2.2µF VCC VIN34 VIN5 C3 2.2µF VCC VIN34 1 8 VIN5 1 EN1 2 10 VIN5 SW1 R2 1M R3 1M R4 1M VCC VO1 VO2 VO3 TP8 13 TP7 12 TP6 11 EN2 3 EN3 4 EN4 14 R1 1M VIN34 EN5 R5 1M VO4 VO5 TP5 10 9 GND 6 VIN5 TP3 5 C2 2.2µF VIN34 7 TP2 TP4 C5 1µF C7 VO2 1µF C6 VO3 1µF VO4 C4 VO5 1µF U1 AAT2605_TDFN33-14 Figure 1: AAT2605 Evaluation Board Schematic. 10 Figure 2: AAT2605 Evaluation Board Top Side Layout.
