TC1301/TC1302 Evaluation Board Installation 2.1 FEATURES The TC1301/TC1302 Evaluation Board has the following features: • • • • • • 2.2 Evaluation of the TC1301A and TC1302A in an 8-pin MSOP Evaluation of the TC1301B and the TC1302B in 3X3 DFN8 package Voltage Detect and RESET Output Capability Device Shutdown Capability Surface-Mount Design Fully Assembled and Tested GETTING STARTED The TC1301/TC1302 Evaluation Board is a fully-functional, assembled and tested surface-mount board for use in evaluation of Microchip’s TC1301/TC1302 Dual Output LDO’s with voltage detect and microcontroller RESET capability (TC1301). This evaluation board has both a TC1301A, in an 8-pin MSOP package, and a TC1302B, packaged in a 3X3 8-pin DFN package. The TC1301A/B integrates two Low Drop Out Linear Regulators with a voltage detect monitor and RESET output, while the TC1302A/B integrates two Low Drop Out Linear Regulators. For the A version, Output Voltage #1 (VOUT1) does not have shutdown capability (the output is present when the input voltage is applied), while Output Voltage #2 (VOUT2) has shutdown capability. For the B version, both VOUT1 and V OUT2 have independent shutdown capability, while VOUT1 is connected internally to the voltage detect monitor (V DET). The TC1301A, which is populated on the evaluation board, is in a MSOP package and has an output configuration of VOUT1 = 2.8V, V OUT2 = 2.6V and VDET = 2.63V. The TC1302B device is packaged in a 3X3 DFN8 and has an output configuration of VOUT1 = 3.3V and VOUT2 = 1.8V. Since there are many combinations available for the TC1301/TC1302 product line, one should consult the product data sheets for more information regarding all output voltage and detect voltage options. The TC1302B position has the RESET pin tied to pin number 1 so that a TC1301A or TC1301B can be evaluated using this board. The TC1301A Evaluation Board was designed to be flexible so that all TC1301A/B and TC1302A/B options could be evaluated using this board. The left position is used to evaluate the A version of TC1301 or TC1302 (no RESET capability). It is populated with small 1 µF ceramic capacitors. The right position is used to evaluate the B version of the TC1301 or TC1302. It is populated with 4.7 µF tantalum capacitors. The TC1301/TC1302 is stable with ceramic or electrolytic capacitors (Tantalum and Aluminum). 2003 Microchip Technology Inc. DS51427A-page 3 TC1301/TC1302 Evaluation Kit User’s Guide TC1301A MSOP8 Description The TC1301A MSOP8 application is located on the left side of the evaluation board. There are eight test points and a two-position switch that are used to apply input voltage to the TC1301A, connect loads for VOUT1 and VOUT2, monitor the RESET output pin and provide shutdown capability for VOUT2. TC1302B 3X3DFN8 Description The TC1302B DFN8 (labeled “TC1301B DFN8” on the test board) is located on the right side of the board. There are seven test points and a two position switch that is used to apply input voltage to the TC1302B, connect loads for VOUT1 and VOUT2 and provide for independent shutdown of both VOUT1 and VOUT2.

The TC1301A and TC1302B can be powered independently or from the same source, if desired. For the TC1301A Connect the positive (+) side of the input voltage source (2.7V to 6.0V) to the VIN test point (TP1) while connecting the negative side of the input voltage supply (-) to the GND test point (TP2). For the TC1302B Connect the positive (+) side of the input voltage source (2.7V to 6.0V) to the VIN test point (TP8) while connecting the negative side of the input voltage supply (-) to the GND test point (TP9). 2.4 CONNECTING LOADS TO THE EVALUATION BOARD Load connections are provided by the board's additional surface-mount test points for the TC1301A application VOUT1 and VOUT2 and the TC1302B VOUT1 and VOUT2 application. For the TC1301A 1. VOUT1 - connect the positive (+) side of the load to the VOUT1 test point (TP3) while connecting the negative side of the load (-) to the GND test point (TP7). 2. VOUT2 - connect the positive (+) side of the load to the VOUT2 test point (TP4) while connecting the negative side of the load (-) to the GND test point (TP6). For the TC1302B 1. VOUT1 - connect the positive (+) side of the load to the Vout1 test point (TP11) while connecting the negative side of the load (-) to the GND test point (TP15). 2. VOUT2 - connect the positive (+) side of the load to the Vout2 test point (TP12) while connecting the negative side of the load (-) to the GND test point (TP14). 2003 Microchip Technology Inc. DS51427A-page 5 TC1301/TC1302 Evaluation Kit User’s Guide 2.5 EVALUATION BOARD FEATURES A two-position switch is used in each application (TC1301A and TC1302B) for feature demonstration. For the TC1301A Switch U2’s position 1 is used to connect VOUT1 to the voltage detect input. The voltage detect input is available on a test point (TP10). With U2’s position 1 OFF (slide to the left), the detect input is only connected to the surface mount test point VDET (TP10). An external voltage can be connected to the VDET pin to evaluate the operation of the RESET function. For the TC1301A, the VDET input is independent of both VOUT1 and VOUT2. With U2 position 2 ON (Slide to the right), the SHDN2 input is pulled high enabling Vout2. The surface mount RESET test point (TP5) is used to monitor the RESET output function of the TC1301A device. If the VDET voltage is below the factory-set threshold (consult Microchip for VDET set point options), the RESET output will be active-low. If the VDET input is above the VDET threshold for approximately 300ms, the RESET output will be high. A 1 nF capacitor is connected from bypass (pin 4) to ground. This optional bypass capacitor is used to improve PSRR and noise characteristics of the LDO outputs. For the TC1302B Switch U5’s position 1 is used to turn VOUT1 ON and OFF. If position 1 is slid to the left, VOUT1 is OFF, if it is slide to the right, VOUT1 is ON. Switch U5’s position 2 is used to turn VOUT2 ON and OFF. If position 2 is slid to the left, VOUT2 is OFF, if it is slide to the right, VOUT2 is ON. The RESET test point (TP13) is connected to Pin 1 of the TC1302B (No Connect). This is done so that a TC1301B DFN8 can be evaluated using the same application as the T1302B. In this case, it is not used. A 10 nF capacitor is connected from bypass (pin 4) to ground. This optional bypass capacitor is used to improve PSRR and noise characteristics of the LDO outputs.
