TLV70215PDBVT is an adjustable linear voltage regulator offering superior performance in a tiny SOT563 6-Pin package. The TLV70215PDBVT unique features include input voltage range down to 0.8 V, optimum performance and allows for improved design methodology for use in other applications. The TLV70215PDBVT is specifically tailored for low voltage, high performance applications that require a wide input voltage range, low quiescent current and numerous protection features.

TLV70215PDBVT offers the highest level of performance for power supply design and circuit requiring very low voltage combined with low power consumption. With this feature, the TLV70215PDBVT can provide excellent regulation performance with a wide input voltage range from 0.8V to 15V and very low dropout voltage of 0.05V.

The regulated output voltage is adjusted by a single external resistor. The regulated output voltage range is 0.8V to 8V with good line and load regulation over the entire input voltage range. The quiescent current is 3 mA at VIN = 5V, VOUT = 5V and the output current can be as high as 500mA at VIN = 3V and VOUT = 0.8V.

TLV70215PDBVT provides various features including input voltage protection against under voltage lockout and over voltage protection. It also has two built-in thermal shutdown circuits, one for over temperature and one for under temperature condition. Additionally, the TLV70215PDBVT has integrated reverse current limiting to prevent current flow back from the output to the input and ensure the best efficiency possible.

TLV70215PDBVT Working Principle:

The TLV70215PDBVT voltage regulator works on the principle of “ideal diode” operation. When input voltage rises above the regulated output voltage, the TLV70215PDBVT will conduct current to regulate the output voltage accordingly. This principle helps to reduce the dropout voltage across the device and increase the efficiency significantly.

The TLV70215PDBVT utilizes an internal LDO pass transistor to regulate the output voltage, with the output voltage being set by the external resistor divider. The current limit protection is controlled by the internal PNP transistor and the over/under temperature protections are provided by the built-in 1V reference. The product also provides internal output voltage monitoring, over voltage protection and input voltage protection.

In summary, the TLV70215PDBVT is an excellent linear voltage regulator that offers a wide input voltage range, low quiescent current and numerous protection features. It provides high level performance for power supply design and circuitry requiring very low voltage combined with low power consumption. The TLV70215PDBVT is well-suited for use in automotive, medical and industrial electronics and is an ideal choice for applications with wide input voltage ranges, miniaturized packages, and low power consumption.
