Its standout feature is a quiescent current of just 300 nA, making it a strong candidate for battery-powered or energy-harvesting designs where the regulator stays on continuously. The 55 dB PSRR at 1 kHz provides enough rejection to clean up ripple from a switching pre-regulator feeding a noise-sensitive load like an RF transceiver or precision ADC reference. ## Package and mounting Housed in a 4-bump DSBGA measuring 0.64 x 0.64 mm, this is a wafer-level chip-scale package. It requires a surface-mount assembly process with fine-pitch stencil and careful solder-paste volume control. ## Protection and control Built-in protection includes over-current, over-temperature, and under-voltage lockout (UVLO). An enable pin allows the system to shut down the regulator when the load is idle, dropping the quiescent current further. The operating temperature range of -40°C to 125°C covers industrial and automotive cabin environments. ## Lifecycle and sourcing No end-of-life notice is on record. For dual-sourcing or a pin-compatible alternate with a different output voltage, the TPS7A0313PDBVR (1.3 V fixed) shares the same PSRR, protection features, and package footprint.","metaTitle":"TI TPS7A0312PYCHR LDO Regulator, 200 mA, 1.2 V Fixed","metaDescription":"TI TPS7A0312PYCHR LDO voltage regulator: 200 mA output, fixed 1.2 V, 300 nA quiescent current, 55 dB PSRR at 1 kHz. 4-DSBGA package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"PSRR":"55dB (1kHz)","Package":"Tape & Reel (TR); Cut Tape (CT)","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"4-XFBGA, DSBGA","lifecycle_stage":"eol_hot","Control Features":"Enable","Current - Output":"200mA","Protection Features":"Over Current, Over Temperature, Under Voltage Lockout (UVLO)","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"-40°C ~ 125°C (TJ)","Voltage - Input (Max)":"6V","Voltage Dropout (Max)":"0.7V @ 200mA","Supplier Device Package":"4-DSBGA (0.64x0.64)","Current - Quiescent (Iq)":"300 nA","Voltage - Output (Min/Fixed)":"1.2V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.50000","currency":"USD"},{"qty":10,"price":"$0.42800","currency":"USD"},{"qty":25,"price":"$0.39960","currency":"USD"},{"qty":100,"price":"$0.31960","currency":"USD"},{"qty":250,"price":"$0.29672","currency":"USD"},{"qty":500,"price":"$0.25108","currency":"USD"},{"qty":1000,"price":"$0.19402","currency":"USD"},{"qty":2500,"price":"$0.17690","currency":"USD"},{"qty":5000,"price":"$0.16549","currency":"USD"},{"qty":12000,"price":"$0.15408","currency":"USD"},{"qty":24000,"price":"$0.14609","currency":"USD"},{"qty":60000,"price":"$0.14266","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/7d6135f0d5b05c2ed04f0031877618f8.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the quiescent current of TPS7A0312PYCHR?","answer":"Quiescent current is 300 nA."},{"question":"Where can I buy TPS7A0312PYCHR?","answer":"This part is sourced and quoted to order through independent distribution.
